LINEAR INTEGRATED CIRCUIT
REAR WINDOW HEATING
TIMER

DESCRIPTION
The bipolar integrated circuit UTC UU6046B is designed as a
window heating timer. Due to time controlled functions, they
reduce the current consumptions of high loads i.e., heating
resistors.
An ON-relay can be switched off after a preset delay time. The
relay time can be interrupted manually, whereas a retrigger
function is not provided.

FEATURES
* Delay time range: 3.7s to 20h
* Relay driver with Z-diode
* RC oscillator determines switching characteristics
* Debounced input for toggle switch
* Two debounced inputs: ON and OFF
* Load-dump protection
* RF interference protected
* Inputs switched to VBatt
