STM6600

STM6601

Smart push-button on/off controller with

Smart ResetTM and 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 CSRD

■ Power-up duration determined primarily by

push-button press (STM6600) or by fixed time

period, tON_BLANK (STM6601)

■ Debounced PB and SR inputs

■ PB and SR ESD inputs withstand voltage up to

±15 kV (air discharge) ±8 kV (contact

discharge)

■ Active high or active low enable output option

(EN or EN) provides control of MOSFET,

DC-DC converter, regulator, etc.

■ Secure startup, interrupt, Smart Reset™ or

power down driven by push-button

■ Precise 1.5 V voltage reference with 1%

accuracy

■ Industrial operating temperature –40 to +85 °C

■ Available in TDFN12 2 x 3 mm package

Applications

■ Portable devices

■ Terminals

■ Audio and video players

■ Cell phones and smart phones

■ PDAs, palmtops, organizers

✓✓

push-pull

open drain(1)

PB must be held low until the

PSHOLD

(2) confirmation

open drain(1)

PB can be released before the

PSHOLD

(2) confirmation

1.

External pull-up resistor needs to be connected to open drain outputs.

2.

For a successful startup, the PSHOLD (Power Supply Hold) needs to be pulled high within specific time, tON_BLANK.
