Brief Description

The KTS1612 is a two input, two output Smart Push-
Button Reset IC. A reset pulse is generated for a
fixed discharge time (400ms typ) after both manual
reset inputs have been held low for the reset request
time of 10s.
The KTS1612 operates over the 2.2 V to 5.5V supply
voltage range, consuming less than 10μA of supply
current at 4V.
The reset and power sequence is controlled by
RST0/RST1 and OFF signals and have the ability to
drive an external P-channel MOSFET. The reset IC
supports two discharge outputs DCHG0 and
DCHG1.
The KTS1612 is available in lead-free, fully green
compliant, small 10-pin UQFN 2.0mm x 1.5mm
package.
