TOSHIBA BiCD IC Silicon Monolithic
TB62300FG
Dual Full-Bridge Driver for DC Motor
The TB62300FG is a dual brushed DC motors driver IC
employing a chopper-based forward/reverse full-bridge
mechanism. It controls two brushed DC motors at high precision.
The motor supply voltage is up to 40 V and the V
DD
supply
voltage is 5.0 V.
Features
A single IC can drive two brushed DC motors.
Monolithic Bi-CMOS IC
Low ON-resistance (R
