TA8052AS

TA8052AS TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC TA8052AS 0.3A MOTOR DRIVER WITH BRAKE FUNCTION The TA8052AS is a full-bridge driver which directly drives a bidirectional DC motor. Inputs DI1 and DI2 are combined to select one of forward, reverse, stop, and brake modes. Since the inputs are TTL-compatible, the IC can be directly controlled from a CPU or other control system. The IC also has various protective functions. FEATURES l Output current : 300mA (max.) l Four modes : Forward, reverse, stop, and brake l Low Standby Current : 100μA (Max.) Weight: 0.7 g (typ.) l Multiple protective functions : Thermal shutdown, current limiter, andovervoltage shut down. l Bulit-in diode for counteracting counter electromotive force l Small SIP-7pin BLOCK DIAGRAM AND PIN LAYOUT 1 2002-02-27 TA8052AS PIN DESCRIPTION PIN No. 1 2 3 4 5 6 7 SYMBOL DI1 DI2 M (+) GND M (−) VCC VS DESCRIPTION Output status control pin. Connects to a PNP-type voltage comparator. Connects to the DC motor. Diodes for absorbing counter electromotive force are contained on the V CC and GND sides. Grounded Connects to the DC motor together with pin 3 and has the same function as pin 3. This pin is controlled by the inputs from pins 1 and 2. Power supply pin. This pin has a function to turn off the output when the applied voltage exceeds 30V, thus protecting the IC and the load. Power supply pin for the control section. This pin is completely separated from the VCC pin. TRUTH TABLE ...
