2 Electrical Characteristics
2.1 Maximum Ratings
Maximum ratings are the extreme limits to which the device can be exposed without permanently damaging it. Do not apply
voltages higher than those shown in the table below.
# Rating
1 Supply Voltage (continuous) (BUSIN,BUSOUT, HCAP)
2 Supply Voltage (pulsed < 400 ms, repetition rate 60s) (BUSIN,BUSOUT, HCAP)
3 CREG, CREGA, PCM, TEST1, TEST2, TEST3, TEST4, TEST5, TEST6, TEST7
BUSIN,BUSOUT, BUSRTN and HCAP Current
4 Maximum duration 1s
5 Continuous
6 Powered Shock (six sides, 0.5 ms duration)
7 Unpowered Shock (six sides, 0.5 ms duration)
8 Drop Shock (to concrete, tile or steel surface, 10 drops, any orientation)
