Features, Applications

The is a monolithic H-Bridge ideal for fractional horsepower DCmotor and bi-directional thrust solenoid control. The IC incorporates internal control logic, charge pump, gate drive, and low RDS(ON) MOSFET output circuitry. The 33886 is able to control continuous inductive DC load currents 5.2 A. Output loads can be Pulse Width Modulation (PWM) controlled at frequencies to 10 kHz. A Fault Status output reports undervoltage, overcurrent, and overtemperature conditions. Two independent inputs control the two halfbridge totem-pole outputs. Two disable inputs force the outputs to tristate (exhibit high impedance). The 33886 is parametrically specified over a temperature range 5.0 V VPWR 28 V, and is available in an economical surface mount package. Features Direct Replacement for MC33186DH1 in the HSOP20 Package 30 V Operation 120 m RDS(ON) H-Bridge Switches TTL /CMOS Compatible Inputs PWM Frequencies to 10 kHz Automatic PWM Overcurrent Limiting Output Short Circuit Protection Overtemperature Output Current Reduction with Shutdown Undervoltage Shutdown Fault Status Reporting

Pin Name AGND FS IN1 Low current Analog signal ground. Open drain active LOW Fault Status output requiring a pull-up resistor 5.0 V. True Logic input control of OUT1 (i.e., IN1 logic HIGH = OUT1 HIGH). Positive power source connection. H-Bridge output 1. Connect these pins to ground in the application. They are test mode pins used in manufacturing only. Device high current power ground. Active LOW input used to simultaneously tristate disable both H-Bridge outputs. When D2 is Logic LOW, both outputs are tristate. H-Bridge output 2. External reservoir capacitor connection for internal Charge Pump. Active HIGH input used to simultaneously tristate disable both H-Bridge outputs. When D1 is Logic HIGH, both outputs are tristate. True Logic input control of OUT2 (i.e., IN2 logic HIGH = OUT2 HIGH).
