MC33982 - Single Intelligent High-Current Self-Protected Silicon High-Side Switch

General Description

Terminal 1 Terminal Name CSNS Formal Name Output Current Monitoring Definition This terminal is used to output a current proportional to the high-side output current and used externally to generate a ground-referenced voltage for the microcontroller to monitor output current.

Key Features

  • The device is suitable for loads with high inrush current, as well as motors and all types of resistive and inductive loads. 33982 SINGLE HIGH-SIDE SWITCH 2.0 mΩ Freescale Semiconductor, Inc Programming, control, and diagnostics are implemented via the Serial Peripheral Interface (SPI). A dedicated parallel input is available for alternate and pulse width modulation (PWM) control of the output. SPI programmable fault trip thresholds allow the device to be adjusted for optimal performance in.
