Delphi Serial Input Driver Module

The Delphi Serial Input Driver Module (SIDM) contains 7 DMOS power FETs. All outputs are fixed as low-side drivers. Four outputs have PWM (pulse width modulated) capability for driving loads at various programmed frequencies from 16 Hz to 32 kHz and various programmed duty cycles from 0% to 100% (DC at 100%). Three outputs only drive loads in a DC manner. Complete load diagnostic capability is provided covering shorts, opens, loss of PWM clock and over-temperature conditions. The SIDM is commanded ON/OFF, programmed for PWM modes and interrogated for faults via SPI bus.

Features

  • Two PWM-capable 1.0 ohm internal DMOS drivers
  • One PWM-capable 0.5 ohm internal DMOS driver
  • One PWM-capable 1.7 ohm internal DMOS driver
  • Three DC-capable 1.7 ohm internal FET drivers
  • Control of DMOS drivers via SPI command inputs
  • SPI bus programming and fault interrogation
  • Current Limit protection of internal DMOS drivers
  • Open and shorted load fault detection
  • Independent driver over temperature protection

Packaging

  • 15-pin JEDEC SIP
  • Wire Type: Gold
  • Wire Size: 2.0 mil
