Delphi Configurable Output Driver
The Delphi Configurable Output Driver (COD) is a user configurable output driver containing 8 DMOS power FETs. Four outputs are configurable as either a high- or low-side driver. Two outputs are fixed as low-side drivers. The remaining two outputs can have the internal DMOS configured high- or low-side drive or can be configured to drive an external FET in a high- or low-side configuration. Complete load diagnostic capablility is provided covering shorts, opens and over-temperature conditions. The COD is configured, commanded ON/OFF and interrogated for faults via a SPI bus.
Features
- Four configurable 1.2 ohm internal DMOS drivers
- Two configurable 1.7 ohm internal DMOS drivers
- Two low-side 1.7 ohm internal DMOS drivers
- Two configurable external FET drivers
- PWM control of external FET drive via discrete inputs
- SPI bus programming and fault interrogation
- Current Limit protection of internal DMOS drivers
- Open and shorted load fault detection
- Over temperature protection
Packaging
- 28-pin SOIC
- Wire Type: Gold
- Wire Size: 1.3 mil
