Description
The bipolar long-term timer LD6046/LD6047 (analog U6046B/U6047B) is designed to automatically limit
the operation time of high loads in the harsh automotive environment with a preset delay time. With the
power-on-reset function the timers guarantee that current consuming devices are not operated
unintentionally.
The delay time can be interrupted manually, but a retrigger function is not provided.
Features
● Delay Time Range: 3.7 s to 20 h
● RC Oscillator Determines Timing Characteristics
● Relay Driver with Z-diode
● Debounced Input for Toggle Switch
● Two Debounced Inputs: ON and OFF
● Load-dump Protection
● RF Interference Protected
● LD6046: Inputs Switched to VBatt
● LD6047: Inputs Switched to ground
