PMIC - Motor and Fan Controllers, Drivers
Freescale Semiconductor
The 33886(MC33886VWR2 ) 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 outputcircuitry. 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 halfbridge 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.
