INTEGRATED CIRCUITS SA5777A Dual air–core gauge driver Product specification Supersedes data of 1997 Feb 24 1999 Sep 20 Philips Semiconductors Philips Semiconductors Product specification Dual air-core gauge driver SA5777A DESCRIPTION The SA5777A is a monolithic driver for controlling air-core (or differential) meters typically used in automotive instrument cluster applications. The circuit interfaces with a microprocessor through a serial bus and directly drives the air-core meter. The SA5777A has 10-bit resolution (0.35 degree) and is guaranteed to be monotonic. Data can be shifted through the part, allowing several SA5777As to be cascaded with only one chip-select line. On-chip current shut down logic protects the circuit from external faults.
