Overview
The Atmel U6032B is a bipolar integrated circuit designed as a toggle switch for automotive applications, controlling electrical loads such as fog lamps, high/low beam, or heated windows.
Key Features
Debounce time: 0.3ms to 6s, RC oscillator determines switching characteristics, relay driver with Z-diode, debounced input for toggle switch, three debounced inputs (ON, OFF, and TOGGLE), load-dump protection, and RF interference protection.
Functional Description
The device has a defined power-on status, and its power supply must be provided with an RC circuit for interference protection and surge immunity. The oscillator frequency is determined by the RzCz circuit, and the relay-control output is an open-collector Darlington circuit with an integrated 23-V Z-diode.
The IC has built-in protection features, including load-dump protection, RF interference protection, and power-on reset, which sets the logic of the circuits to a defined initial condition.
