SA5778D Datasheet Serial Triple Gauge Driver Stgd

Manufacturer: Philips Semiconductors (now NXP Semiconductors)

Overview: INTEGRATED CIRCUITS SA5778 Serial triple gauge driver (STGD) Product specification Supersedes data of 1997 May 27 IC18 Data Handbook 1998 Apr 03 Philips Semiconductors Philips Semiconductors Product specification Serial.

General Description

The Serial Triple Gauge Driver (STGD), is a single chip air core driver providing drive to one major gauge, and two minor gauges, for automotive applications such as Speedometer, Fuel, Temperature, Tachometer, Volts, and Oil pressure information display.

The STGD operates in conjunction with a microcontroller receiving serial data inputs, and can provide status back to the microcontroller either serially or via a status line.

The protocol is compatible with the Philips Single Gauge Driver (SGD) and Dual Gauge Driver (DGD).
