Features

• Operating voltage 1.6 V to 5.5 V

• Low standby current of 0.6 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

Startup process

STM6600 open drain(1) ✓

✓

Push-pull

Open drain(1)

PB must be held low until the

PSHOLD(2) confirmation

STM6601 open drain(1) ✓

✓

Push-pull

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.
