KTS1612 Smart Push-Button Reset with Two Discharge Paths Features Brief Description Operating Range: 2.2V~5.5V The KTS1612 is a two input, two output Smart Push- Supply Current in standby: < 1A (VDD = 4V) Button Reset IC. A reset pulse is generated for a Quiescent Current in Ship mode: < 1A (VDD = 4V) fixed discharge time (400ms typ) after both manual Output Delay time (RST0 & 1 Input pins): 10s Typ. reset inputs have been held low for the reset request Reset Pulse Time (SRO, nSRO Output): 400ms Typ. time of 10s. Ship Mode Entry Delay Time (OFF Input): 15s The KTS1612 operates over the 2.2 V to 5.5V supply Ship Mode Entry Command (OFF Input): 5 cycles voltage range, consuming less than 10A of supply Ship Mode Exit Delay Time (RST0 Input): Typ. 2s current at 4V. Output Discharge Time: 400ms Typ. Output Discharge Delay Time: 6ms Max The reset and power sequence is controlled by ESD Protection RST0/RST1 and OFF signals and have the ability to Human Body Model: 2kV drive an external P-channel MOSFET. The reset IC Charged Device Model: 1.5kV supports two discharge outputs DCHG0 and Over-Temperature Protection DCHG1. -40C to +85C Temperature Range The KTS1612 is available in lead-free, fully green compliant, small 10-pin UQFN 2.0mm x 1.5mm package.
