Description

The MC33143 is a dual highside 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 SMARTMOSE 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 highside 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.
• Designed to Operate Over Wide Supply Voltages of 5.5 V to 26 V
• Dual HighSide Outputs Clamped to 10 V for Driving Inductive Loads
• Internal Charge Pump for Enhanced Gate Drive
• Interfaces Directly to a Microcontroller with Parallel Input Control
• Outputs Current Limited to 3.0 A to 6.0 A for Driving Incandescent Loads
• Chip Enable "Sleep Mode" for Power Conservation
• Individual Output Status Reporting
• Fault Interrupt Output for System Interrupt Use
• Output ON or OFF Open Load Detection
• Overvoltage Detection and Shutdown
• Output Over Temperature Detection and Shutdown with Automatic Retry
• Sustained Current Limit or Immediate Overcurrent Shutdown Output Modes
• Output Short to Ground Detection and Shutdown with Automatic Retry
• Output Short to VPwr Detection
