The MAX162BCWG is an integrated circuit (IC) component manufactured by Maxim Integrated. It is a voltage supervisor and watchdog timer with a built-in 4-channel sequencer. This IC is designed to monitor power supply voltage levels, supervise microcontrollers, and provide reset and system control functions. It is used in various applications to ensure reliable system operation and prevent data corruption or malfunctioning due to power supply anomalies.
The key features of the MAX162BCWG are as follows:
1. Voltage Supervision: The IC has four independent voltage monitor inputs, labeled V1 to V4. These inputs are used to monitor power supply voltage levels and detect any overvoltage or undervoltage conditions. Each voltage monitor input has a dedicated active-low open-drain output (OUT1 to OUT4) that can be used to control external devices or trigger a system reset.
2. Watchdog Timer: The MAX162BCWG includes a watchdog timer to monitor the activity of microcontrollers or other digital devices. The watchdog timer can be programmed using an external capacitor to set the timeout period. If the microcontroller fails to reset the watchdog timer within the specified time, the MAX162BCWG generates a system reset.
3. Sequencer: This IC has a built-in 4-channel sequencer that allows controlled power-up and power-down sequences for multiple power supplies. Each sequencer input (IN1 to IN4) can be independently enabled or disabled using external logic signals
