TA7279AP

TA7279P/AP TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC TA7279P,TA7279AP DUAL BRIDGE DRIVER The TA7279P, TA7279AP are dual bridge driver designed for DC motor rotation control. FEATURES l Wide Range of Operating Voltage : V CC (opr.) = 6~18 V (P, AP), V S (opr.) = 0~16 V (P) / = 0~18 V (AP) l Output Current Up to 1.0 A (AVE.), 3.0 A (PEAK) l Built−in Thermal Shut Down and Current Limiter l Input Hysteresis for Stable Operation BLOCK DIAGRAM Weight: 3.00 g (Typ.) 1 2001-06-13 http://www.Datasheet4U.com TA7279P/AP PIN FUNCTION PIN No. 1V 2V 3 4 OUT1 5V 6 OUT2 7 8 GND 9 OUT2 10 V 11 OUT1 12 V 13 V 14 V −B B S −B SYMBOL IN2−A IN2−A FUNCTIONAL DESCRIPTION A−ch input terminal A−ch input terminal −ch output terminal A−ch Motor drive power supply −ch output terminal GND terminal −ch output terminal B−ch Moter drive power supply −ch output terminal B−ch input terminal B−ch input terminal Logic power supply VI N1−A −A A S−A −A A GND −B B IN1−B IN2−B CC 2 2001-06-13 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 c ircuit is an ac tive hig h t ype, as shown in t he diag ram. Wh en voltage higher t han t he spec ified 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”. Si nce the input current IN flows to the inpu...
