STM6601 fiche technique
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
TDFN12
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.
