The AD5100 is a system management IC from Analog Devices for automotive applications. It has 6 factory programmed monitoring inputs and 2 device enabling outputs. The device has two 30 V monitoring inputs that can be used to control external device shutdown. AD5100 also has factory programmed overvoltage, undervoltage, turn-on and turn-off thresholds and shutdown timings. Shutdown warning with fault detection is available through AD5100. AD5100 also has 5 V and 7.96 V monitoring inputs that can be used to control external device reset. The device also has factory programmed reset thresholds and hold time. AD5100 also has two monitoring functions: watchdog reset controller and optional floating input. AD5100 also has digital interface and programmability for external devices.
The AD5100 System Management IC provides four programmable voltage‑monitoring inputs (two high‑voltage 30 V channels and two low‑voltage channels) and a watchdog reset controller. It is qualified for automotive, network equipment, computer and embedded controller applications and operates from a 6 V to 30 V supply.
The device features an I2C‑compatible serial interface, factory‑programmed thresholds, and optional dynamic adjustments via OTP. It is supplied in a 16‑lead QSOP package and supports operation from –40 °C to +125 °C.
