STM6601

Smart push-button on/off controller with

Smart Reset^TMand power-on lockout

Features

■ Operating voltage 1.6 V to 5.5 V

■ Low standby current of 1 µA

■ Adjustable Smart Reset™ assertion delay time

driven by external C

SRD

■ Power-up duration determined primarily by

push-button press (STM6600) or by fixed time

period, t

(STM6601)

ON_BLANK

■ Debounced PB and SR inputs

■ PB and SR ESD inputs withstand voltage up to

15 kV (air discharge) 8 kV (contact

discharge)

TDFN12

■ Active high or active low enable output option

(EN or EN) provides control of MOSFET,

DC-DC converter, regulator, etc.

Applications

power down driven by push-button

■ Portable devices

■ Terminals

■ Precise 1.5 V voltage reference with 1%

accuracy

■

Audio and video players

■ Industrial operating temperature –40 to +85 °C

■ Available in TDFN12 2 x 3 mm package

■ Cell phones and smart phones

■ PDAs, palmtops, organizers
