Serial triple gauge driver (STGD)

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).
The STGD also includes a protected battery supply for external
single Serial Gauge Drivers or Dual Gauge Drivers.
