Description
Sequential Dual-Bridge Driver (Driver for Switching between Forward and Reverse Rotation) for DC Motor
Manufacturer
TOSHIBA [Toshiba Semiconductor]
Datasheet
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
motor voltage facilitates motor voltage adjustment. The IC
requires little input current, enabling direct connection with
CMOS.
Features
