TA7257P

TA7257P TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC TA7257P BRIDGE DRIVER The TA7257P is a Full Bridge Driver for blashed DC Motor Rotation control. Forward Rotation, Reverse Rotation, Stop and Braking operations are available. It’s designed for Loading and Reel Motor driver for VTR and Tape Deck, and any other consumer and industrial applications. TA7257P have Operation Supply Voltage terminal and Motor Driving Supply Voltage terminal independently therefore Servo control operation is applicable. FEATURES l Output Current Up to 1.5 A (AVE.), and 4.5 A (PEAK). l 4 Function Modes (CW, CCW, STOP and Brake) are Controlled by 2 Logic Signals Fed Into 2 Input Terminals. l Build in Over Current Protector and Thermal Shut Down Circuit. l Operating Voltage Range: VCC (opr.) = 6~18 V, VS (opr.) = 0~18 V BLOCK DIAGRAM Weight: 1.88 g (Typ.) 1 2001-08-27 PIN FUNCTION PIN No. 1 2 3 4 5 6 7 SYMBOL FUNCTIONAL DESCRIPTION IN1 IN2 OUT1 GND OUT2 VS VCC Input terminal Input terminal Output terminal GND terminal Output terminal Supply voltage terminal for Motor drive Supply voltage terminal for Logic FUNCTION IN1 1 0 1 0 IN2 1 1 0 0 OUT1 L L H OUT2 L H L MODE Brake CW / CCW CCW / CW Stop MAXIMUM RATINGS (Ta = 25°C) CHARACTERISTIC Peak Supply Voltage Peak Operate Output Current PEAK AVE.
