TA7291P,TA7291S,TA7291F
BRIDGE DRIVER
The TA7291P / S / F are Bridge Driver with output voltage
control.
FEATURES
l 4 modes available (CW / CCW / STOP / BRAKE)
l Output current: P type 1.0 A (AVE.) 2.0 A (PEAK)
S / F type 0.4 A (AVE.) 1.2 A (PEAK)
l Wide range of operating voltage: VCC (opr.) = 4.5~20 V
VS (opr.) = 0~20 V
Vref (opr.) = 0~20 V
l Build in thermal shutdown, over current protector and punch
= through current restriction circuit.
l Standby mode available (STOP MODE)
l Hysteresis for all inputs.
