RESET TIMER IC FOR MOBILE EQUIPMENTS

DESCRIPTION

The UTC UIC832 is a reset timer IC for mobile equipment which

require long interval for reset sequence. The long interval prevents

unexpected resets caused by accidental key operations.

When both active-low input pins (SR0 and SR1) are activated at

the same time, the UTC UIC832 will generate reset signals after

output delay time.

UTC UIC832X-Q, UIC832B-R, or UTC UIC832X-T:

A reset signal will be released automatically after output release

time or by making one of the active-low input pins high, a reset

signal can be released before output release time.

Output delay time is fixed.

The UTC UIC832 provides ultra-low supply current while a reset

signal is remaining active or after being sent out.
