Panasonic brushed DC motor series consists of the single motor driver ICs and the dual motor driver ICs.
This series has two ICs, AN44070A and AN41402A, each of which contains two drive circuits to simultaneously drive two DC motors, saving mounting space.
The NFAULT pin is provided for detection of abnormal conditions (undervoltage, overtemperature, and overcurrent [load short-circuit]).
With the TJMON pin, it is possible to detect the temperature of the IC chip by calculating using the difference between the TJMON pin voltages before and after motor operation.
All low-voltage driver ICs use Wafer Level Chip Size Package (WLCSP), saving mounting space.
Dramatically low output ON-resistance compared to previous model, achieving ultra-low loss.
The consumption current of IC can be reduced in standby operation, saving energy.In particular, AN41406A consumes almost zero current at standby, enabling longer battery life.
