Description
The IMP62C548A-48 is an electronic component in the form of an IC chip. It is designed to simplify power supply monitoring and control in microprocessor systems. This circuit incorporates four functions, including reset control, watchdog monitoring, battery backup switching, and power-failure monitoring. With its design improvements over the Maxim MAX690A/692A/802L/802M/805L, it offers lower current consumption, precision supply-voltage monitor options, a built-in battery-backup power switch, a watchdog timer, and power failure/low battery detection. The IMP62C548A-48 also features short-circuit protection, thermal limiting, and a compact 8-pin SO package. It is suitable for various applications, including embedded control systems, battery-operated systems, intelligent instruments, wireless communication systems, PDAs, handheld equipment, and microprocessor/microcontroller power supply monitoring.
