Full-Bridge Driver for DC Motors (driver for controlling the forward and reverse rotations)
The TA7291AP/TA7291AS (J)/TA7291AF is a full-bridge driver to
control the forward and reverse rotations. Each driver can select
one of four modes: CW, CCW, stop, brake.
The TA7291AP is designed to provide output currents of 1.0 A (typ.)
and 2.0 A (peak). The TA7291AS (J)/TA7291AF is designed to
provide output currents of 0.4 A (typ.) and 1.2 A (peak).
There are two different power supply pins for each driver: one on
the output side and the other on the control side of the driver. Also,
there is the Vref pin on the output side. This pin is available for
adjusting the voltage supplied to the motor.
The input circuit of the driver is compatible with CMOS logic
because it draws a small amount of input current.
Features
· Wide range of operating voltage: VCC (opr.) = 4.5 V to 27 V
: VS (opr.) = 4.5 V to 27 V
: Vref (opr.) = 4.5 V to 27 V
Vref must be VS.
· Output current: AP type 1.0 A (typ.) 2.0 A (peak)
: AS (J)/AF type 0.4 A (typ.) 1.2 A (peak)
· Thermal shutdown and overcurrent protection
· Flyback diodes
· Hysteresis for all inputs
· Standby mode available
