TA8440H/F TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC TA8440H,TA8440F DC MOTOR FULL BRIDGE DRIVER F TYPE: UNDER DEVELOPMENT The TA8440H is a full−bridge driver for selecting the forward and reverse running of a motor with brushes and is able to control 4 modes of forward, reverse, stop and braking. The motor driving unit and the control unit have a separate power supply line, independently and the TA8440H is also usable as a stepping motor driver. TA8440H FEATURES l Output current is as large as 1.5A (AVE) and 3.0A (PEAK). TA8440F (Under development) l 4 modes of forward, reverse, stop, and braking are available and a counter−electromotive force absorbing diode has been built−in. l Thermal shutdown circuit incorporated. l Input is compatible with CMOS. l Built−in input pull−up resistor. BRAKE = 200 kΩ (Typ.) l Built−in input pull−down resistor. IN, ENABLE = 100 kΩ (Typ.) Weight HZIP12-P-1.78B: 4.04 g (Typ.) HSOP20-P-450-1.00: 0.79 g (Typ.)
