ROHM's new H-bridge driver LSI series incorporates a new VREF variable system for driving brush-commutated motors with low power consumption without changing the input voltage level. This simplifies replacement while providing optimum motor drive operation with minimal design changes. ROHM's entire series of H-bridge drivers support a wide range of supply voltages (3V to 36V) and output currents (up to 2A) and achieves lower circuit current under no load conditions — 1/10-1/20 that of conventional LSIs. In addition, power-saving circuit is integrated to suppress standby current, contributing to energy efficient circuit design.
BD6221F Features:
Incorporates a new VREF variable system for high efficiency operation with low power consumption. Part replacement is simplified as well.
Allows direct PWM control, and the optimized circuit ensures high-speed response and enables PWM duty control.
Low standby current (0μA) under motor stop condition.
Integrates a shoot-through prevention circuit.
Equipped with output protection circuits for overcurrent, overvoltage, overheating, and under-voltage lock out.
Supports TTL input.
MOSFET on the output stage can achieve small number of external components.
