Product Overview

The KIT33988CEVBE is an evaluation module for 33988, a dual self protected 8mΩ silicon switch used to replace electromechanical relays, fuses and discrete devices in power management applications. The 33988 is designed for harsh environment and includes self recovery 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 application.
  • Dual 8mΩ max high side switch with parallel input or SPI control
  • 6V to 27V operating voltage with standby currents less then 5µA
  • Output current monitoring with two SPI selectable current ratios
  • SPI control of over current limit, over current fault blanking time, output OFF open load detection
  • SPI status reporting of over current, open and shorted loads, over temperature shutdown
  • Enhanced -16V reverse polarity VPWR protection
