The ISL78420 is a 100V, 2A high frequency half-bridge NMOS FET driver with a tri-level PWM input. With an operating supply voltage range of 8V to 14V, it supports a 114V bootstrap bias for driving the high-side NMOS in 100V half-bridge applications. This part is a derivative of the industrial family of HIP2120-HIP2123 100V half-bridge drivers.
This driver is designed to work in conjunction with the ISL78220and ISL78225 “Multi-Phase Interleaved Boost PWM Controller with Light Load Efficiency Enhancement”. It can also be used in applications where a standard half-bridge driver is needed.
This driver has a programmable dead-time to ensure break-before-make operation between the high-side and low-side MOSFET. A resistor is used to set the dead-time from 35ns to 220ns.
The PWM pin’s tri-level input allows control of the high-side and low-side drivers with a single pin. When the PWM input is at logic high, the high-side bridge FET is turned on and the low-side FET is off. When the input is at logic low, the low-side bridge FET is turned on and the high-side FET is turned off. When the input voltage is in mid-level state, both the high and low-side bridge FETs are turned off. The enable pin (EN), when low, also turns both bridge FETs off. This EN input can be used when the controller driving the ISL78420 does not utilize a tri-level output. Both PWM and EN logic inputs are V_DD tolerant.
The ISL78420 is offered in a 14 Ld HTSSOP package and complies with 100V conductor spacing per IPC-2221. The device is Automotive AEC-Q100 qualified for the temperature range of -40°C to +125°C.

The ISL78225 4-phase controller is targeted for applications where high efficiency (95%) and high power are required. The multiphase boost converter architecture uses interleaved timing to multiply channel ripple frequency and reduce input and output ripple. Lower ripple results in fewer input/output capacitors and therefore lower component cost and smaller implementation area.
The ISL78225 has a dedicated pin to initiate the phase dropping scheme for higher efficiency at light load by dropping phases based on the load current, so the switching and core losses in the converter are reduced significantly. As the load increases, the dropped phase(s) are added back to accommodate heavy load transients and improve efficiency.
Input current is sensed continuously by measuring the voltage across a dedicated current sense resistor or inductor DCR. This current sensing provides precision channel-current balancing, and per-phase overcurrent protection. A separate totalizing current limit function provides overcurrent protection for all the phases combined. This two-stage current protection provides maximum performance and circuit reliability.
ISL78225 can also provide for input voltage tracking via the VREF2 pin. The comparison reference voltage will be the lower of the VREF2 pin or the internal 2V reference. By using a resistor network between VIN and VREF2 pin, the output voltage can track input voltage to limit the output power during automotive cranking conditions.
ISL78225 can output a clock signal for expanding operation to 8 phases, which offers high system flexibility. The threshold-sensitive enable input is available to accurately coordinate the start-up of the ISL78225 with any other voltage rail.

The HA-2556 is a monolithic, high speed, four quadrant, analog multiplier constructed in the Intersil Dielectrically Isolated High Frequency Process. The voltage output simplifies many designs by eliminating the current-to-voltage conversion stage required for current output multipliers. The HA-2556 provides a 450V/µs slew rate and maintains 52MHz and 57MHz bandwidths for the X and Y channels respectively, making it an ideal part for use in video systems.
The suitability for precision video applications is demonstrated further by the Y-Channel 0.1dB gain flatness to 5.0MHz, 1.5% multiplication error, -50dB feedthrough and differential inputs with 8µA bias current. The HA-2556 also has low differential gain (0.1%) and phase (0.1°) errors.
The HA-2556 is well suited for AGC circuits as well as mixer applications for sonar, radar, and medical imaging equipment. The HA-2556 is not limited to multiplication applications only; frequency doubling, power detection, as well as many other configurations are possible.

The ISL78220 6-phase controller is targeted for applications where high efficiency (95%) and high power are required. The multiphase boost converter architecture uses interleaved timing to multiply channel ripple frequency and reduce input and output ripple. Lower ripple results in fewer input/output capacitors and therefore lower component cost and smaller implementation area.
The ISL78220 has a dedicated pin to initiate the phase dropping scheme for higher efficiency at light load by dropping phases based on the load current, so the switching and core losses in the converter are reduced significantly. As the load increases, the dropped phase(s) are added back to accommodate heavy load transients and improve efficiency.
Input current is sensed continuously by measuring the voltage across a dedicated current sense resistor or by inductor DCR. This current sensing provides precision channel-current balancing, and per-phase overcurrent protection. A separate totalizing current limit function provides overcurrent protection for all the phases combined. This two-stage current protection provides maximum performance and circuit reliability.
The ISL78220 can also provide for input voltage tracking via the VREF2 pin. The comparison reference voltage will be the lower of the VREF2 pin or the internal 2V reference. By using a resistor network between VIN and VREF2 pin, the output voltage can track input voltage to limit the output power during automotive cranking conditions.
The ISL78220 can output a clock signal for expanding operation to 12 phases, which offers high system flexibility. The threshold-sensitive enable input is available to accurately coordinate the start-up of the ISL78220 with any other voltage rail.
