NTE7196 integrated circuit h-bridge with motor control description: the NTE7196 is a 3a h-bridge in an 1 1-lead staggered sip type package designed for m otion con\ trol applications. the device is built using a multi-technology process which combines bipolar and cmos control circuitry with dmos power devices on the same monolithic structure. the h-bridge configuration is ideal for driving dc and stepper motors. the NTE7196 accommodates peak output currents up to 6a. current sensing can be achieved via a small sense resistor connected in series with the power ground lead. for current sensing without disturbing the path of current to the load, the NTE7196 is recommended. features: delivers up to 3a continuous output operates at supply voltages up to 55v low r ds(on) typically 0.33 per switch ttl and cmos compatible inputs no shoot-through current thermal warning flag output at +145 c thermal shutdown (outputs off) at +170 c internal clamp diodes shorted load protection internal charge pump w/external bootstrap capability applications: dc and stepper motor drives position and velocity servomechanisms factory automation robots numerically controlled machinery computer printers and plotters absolute maximun ratings: (note 1) total supply voltage (v s , pin6) 60v . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . voltage at pins 3, 4, 5, and 9 12v . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . voltage at bootstrap pins (pin1 and pin11) v out + 16v . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . peak output current (200ms) 6a . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . continuous output current 3a . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . power dissipation (note 2) 25w . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . sense voltage (pin7 to pin8) +0.5v to -1.0v . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . power dissipation (t a = +25 c, free air) 3w . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . junction temperature, t j(max) 150 c . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . esd susceptibility (note 3) 1500v . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . storage temperature, t stg - 40 to +150 c . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . lead temperature (soldering, 10 sec.) +300 c . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
