STM6600, STM6601 1 Description Description The STM6600-01 devices monitor the state of connected push-button(s) as well as sufficient supply voltage. An enable output controls power for the application through the MOSFET transistor, DC-DC converter, regulator, etc. If the supply voltage is above a precise voltage threshold, the enable output can be asserted by a simple press of the button. Factoryselectable supply voltage thresholds are determined by highly accurate and temperaturecompensated references.

STM6600, STM6601 2 Pin descriptions Pin descriptions VCC - power supply input VCC is monitored during startup and normal operation for sufficient voltage level. Decouple the VCC pin from ground by placing a 0.1 µF capacitor as close to the device as possible. SR - Smart Reset™ button input This input is equipped with voltage detector with a factory-trimmed threshold and has ±8 kV HBM ESD protection.
Pin descriptions STM6600, STM6601 PB - power ON switch This input is equipped with a voltage detector with a factory-trimmed threshold and has ± 8 kV HBM ESD protection. When the PB button is pressed and held, the battery voltage is detected and EN (or EN) is asserted if the battery voltage is above the threshold VTH+ during the whole tDEBOUNCE period (see Figure 13).
STM6600, STM6601 Pin descriptions EN or EN - enable output This output is intended to enable system power (see Figure 1). EN is asserted high after a valid turn-on event has been detected and confirmed (i.e. push-button has been pressed and held for tDEBOUNCE or more and VCC > VTH+ voltage level has been detected - see Figure 13).
Operation 3 STM6600, STM6601 Operation The STM6600-STM6601 simplified smart push-button on/off controller with Smart Reset™ and power-on lockout enables and disables power for the application depending on pushbutton states, signals from the processor, and battery voltage. Power-on Because most of the processors have outputs in high-Z state before initialization, an internal pull-down resistor is connected to PSHOLD input during startup (see Figure 7, 8, 9, 10, 11, 12, 13, and 18).
STM6600, STM6601 Operation If an undervoltage condition is detected for tDEBOUNCE + tINT_Min + tSRD, the enable output is deasserted (see Figure 21).
