FEATURES

 An ultra-fine CMOS process has been adopted for low power consumption in a design with no charge-pump.

 A small 24-pin QFN package (4*4mm / t=0.8mmMax / Lead pitch 0.4mm) has been adopted.

 All bridges can be driven simultaneously.

 Constant-Voltage control H-bridges Drive; Accuracy±5%(at CV DAC=4.0V)

 Constant-Current H-bridges Drive; Accuracy±5%(at CC DAC=200mV)

 A constant voltage value and a constant current value are set as arbitrary values by serial setup (4-bit).

 External resistance is unnecessary in order to change by Built-in DAC.

 Built-in thermal shutdown circuit.(shut: 150℃/return: 120℃/Hysterisis: 30℃)

 Built-in UVLO shutdown circuit.(shut: 1.8V/return: 2.0V/Hysterisis: 0.2V)

 Built-in CC mode weak excitation

 H-Bridge Drive Type/ON Resistance
