General Description

of many of these pins can be found in the Functional Pin Description section beginning on page 16.

Pin 1 Pin Name CSNS Pin Function Output Formal Name Output Current Monitoring Definition This pin is used to output a current proportional to the designated HS0-1 output.

Key Features

  • The device is suitable for loads with high inrush current, as well as motors and all types of resistive and inductive loads. 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 each output. SPI-programmable fault trip thresholds allow the device to be adjusted for optimal performance in the.
