Overview
Order this document by MC33143/D Advance Information MC33143 Dual High-Side Switch The MC33143 is a dual high–side switch designed for solenoid control in harsh automotive applications, but is well suited for other environments.
The device can also be used to control small motors and relays as well as solenoids.
The MC33143 incorporates SMARTMOS™ technology, with CMOS logic, bipolar/MOS analog circuitry, and DMOS power outputs.
An internal charge pump is incorporated for efficient gate enhancement of the internal high–side power output devices.
The outputs are designed to provide current to low impedance solenoids.
The MC33143 provides individual output fault status reporting along with internal Overcurrent and Over Temperature protection.
The device also has Overvoltage protection, with automatic recovery, which “globally” disables both outputs for the duration of an Overvoltage condition.
Each output has individual Overcurrent and Over Temperature shutdown with automatic retry recovery.
Outputs are enabled with a CMOS logic high signal applied to an input to providing true logic control.
The outputs, when turned on, provide full supply (battery) voltage across the solenoid coil.
The MC33143 is packaged in an economical 24 pin surface mount power package and specified over an operating voltage of 5.
5 V ≤ VPwr < 26 V for –40°C ≤ TA ≤ 125°C.
