AD5100與工廠編程電壓監(jiān)測和監(jiān)督職能四系統(tǒng)管理集成電路

　　The AD5100 is a factory programmed system management IC that combines four channels of voltage monitoring and watchdog supervision. The AD5100 can be used to shut down external supplies， reset processors， or disable any other system electronics when the system malfunctions. The AD5100 can also be used to protect systems from improper device power-up sequencing. The AD5100 is a robust watchdog reset controller， and can monitor two 30 V inputs with shutdown and reset controls， one 2.3 V to 5.0 V input， and one 1.6 V to 7.96 V input. Most monitoring input thresholds and timing settings have a range of settings which are factory programmed by Analog Devices， Inc. in the one-time programmable EPROM （OTP） memory， or can be programmed on-the-fly over the serial interface.

　　The AD5100 is versatile for system monitoring applications where critical microprocessor， DSP， and embedded systems operate under harsh conditions， such as automotive， industrial， or communications network environments.

　　The AD5100 is available in a compact 16-lead QSOP package and can operate in an extended automotive temperature range from ?40°C to +125°C.

　　Analog Devices provides non-OTP programmed AD5100 parts for use in evaluating the desired threshold and delay settings. Only factory programmed AD5100 parts are shipped in production quantities. Contact Analog Devices directly to inquire about factory programmed models.
