MC33886

Freescale Semiconductor Technical Data Document Number: MC33886 Rev 10.0, 01/2014 5.0 A H-Bridge The 33886 is a monolithic H-Bridge ideal for fractional horsepower DC-motor 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 up to 5.0 A. Output loads can be pulse width modulated (PWM-ed) at frequencies up to 10 kHz. A Fault Status output reports undervoltage, short-circuit, and overtemperature conditions. Two independent inputs control the two half-bridge totem-pole outputs. Two disable inputs force the H-Bridge outputs to tri-state (exhibit high-impedance). The 33886 is parametrically specified over a temperature range of -40 C  TA  125 C, 5.0 V  V+  28 V. The IC can also be operated up to 40 V with derating of the specifications. The IC is available in a surface mount power package with exposed pad for heatsinking. This device is powered by SMARTMOS technology. 33886 H-BRIDGE Features 5.0 V to 40 V continuous operation 120 m RDS(on) H-Bridge MOSFETs TTL /CMOS compatible Inputs PWM frequencies up to 10 kHz Active current limiting via internal constant off-time PWM (with temperature-dependent threshold reduction) Output short-circuit protection Undervoltage shutdown Fault status reporting VW SUFFIX (PB-FREE) 98ASH70702A 20-PIN HSOP Applications Automotive systems DC motor contr...
