TA7288P
Sequential Dual-Bridge Driver (Driver for Switching between Forward and Reverse
Rotation) for DC Motor
The TA7288P is a bridge driver that is ideal for normal / reverse
switching.
This circuit offers four modes: normal rotation, reverse rotation,
stop, and brake.
The output current is 1.0 A (AVE.) and 2.0 A (PEAK). TA7288P
has an ideal circuit configuration for VCR front tape loading and
offers two types of power supply pins. One is for output, the other
for control. The V_ref pin on the output side used to control the
motor voltage facilitates motor voltage adjustment. The IC
requires little input current, enabling direct connection with
CMOS.
Weight: 2.47 g (typ.)
Features
z Wide range of operating voltage: V_CC (opr.) = 4.5 to 18 V
V_S (opr.) = 0 to 18 V
V_ref (opr.) = 0 to 18 V
No malfunction occurs even if V_CC is higher than V_S or vice versa. however, observe V_ref ≤ V_S.
z Output current up to 1.0 A (AVE.) and 2.0 A (PEAK)
z Built-in thermal shutdown circuit and overcurrent protection circuit for output pins
z Built-in punch−through current restriction circuit
z Built-in back electromotive force absorber diode
z Built-in hysteresis circuit
