TA7291AP/AS(J)/AF TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA7291AP,TA7291AS(J),TA7291AF 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.
