TA7279P/AP TA7279P/AP TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC TA7279P TA7279P,TA7279AP TA7279AP DUAL BRIDGE DRIVER The TA7279P TA7279P, TA7279AP TA7279AP are dual bridge driver designed for DC motor rotation control. FEATURES Wide Range of Operating Voltage : VCC (opr.) = 6~18 V (P, AP), VS (opr.) = 0~16 V (P) / = 0~18 V (AP) Output Current Up to 1.0 A (AVE.), 3.0 A (PEAK) Built-in Thermal Shut Down and Current Limiter Input Hysteresis for Stable Operation BLOCK DIAGRAM Weight: 3.00 g (Typ.) 1 2001-06-13 TA7279P/AP TA7279P/AP PIN FUNCTION PIN No. SYMBOL FUNCTIONAL DESCRIPTION 1 VIN2-A 2 VIN2-A 3 VI N1-A 4 OUT1-A 5 VS-A 6 OUT2-A 7 GND 8 GND 9 OUT2-B 10 VS-B 11 OUT1-B 12 VIN1-B B-ch input terminal 13 VIN2-B B-ch input terminal 14 VCC Logic power supply A-ch input terminal A-ch input terminal A-ch output terminal A-ch Motor drive power supply A-ch output terminal GND terminal B-ch output terminal B-ch Moter drive power supply B-ch output terminal 2 2001-06-13 TA7279P/AP TA7279P/AP APPLICATION NOTE (1) Input circuit Input terminals of (2), (3), (12) and (13) Pin are all high active type and have a hysteresis. 3 µA Typ. of input current is required. The input circuit is an active high type, as shown in the diagram. When voltage higher than the specified VIN (H) is applied, the output is logic "H". When voltage lower than the specified VIN (L) is applied or if the input is grounded, the output is logic "L". Since the input current IN flows to the input when logic "H", be careful with the output impedance at the previous step.

VFU, L 6 2001-06-13 TA7279P/AP TA7279P/AP APPLICATION CIRCUIT Problems may result if a capacitor is inserted in parallel to the motor as a measure against noise. If measures against noise are necessary, connect capacitors as shown in the diagram below. A larger bypass capacitor between VCC and GND is effective against noise and other problems. (A capacitance higher than 100 µF is recommended.) Note: Utmost care is necessary in the design of the output line, VS and GND line since IC may be destroyed due to short-circuit between outputs, air contamination fault, or fault by improper grounding. 7 2001-06-13 TA7279P/AP TA7279P/AP PACKAGE DIMENSIONS HDIP14-P-500-2 HDIP14-P-500-2.54A Unit: mm Weight: 3.00 g (Typ.) 8 2001-06-13 TA7279P/AP TA7279P/AP RESTRICTIONS ON PRODUCT USE 000707EBA 000707EBA · TOSHIBA is continually working to improve the quality and reliability of its products.
