Product overview
Description
The Smart Reset™ devices provide a useful feature that ensures inadvertent short reset push-button closures do not cause system resets. This is done by implementing an extended Smart Reset™ input delay time (Tr) and combined push-button inputs, which together ensure a safe reset and eliminate the need for a specific dedicated reset button.
The STM6620S has two combined delayed Smart Reset™ inputs (RST0 and RST1) with a preset, delayed, Smart Reset™ setup time (Tr). The reset output is asserted after both the Smart Reset™ inputs are in a predefined state during the Tr delay time. The reset outputs then remain active during Td. Two outputs are available, one is active low (nSR0) while the other is active high (SR0). SR0 is capable of driving en external PMOS to connect or disconnect the battery.
The STM6620S also offers two discharge paths to ensure a correct system setup before the complete restart of a smartphone. A dedicated pin is able to detect if a voltage is present on the USB connector, which means the charger is plugged in.
This device fully operates over the broad supply voltage range of 2.2 V to 5.5 V and over the industrial temperature range -40 °C to 85 °C.
