TPV803/809/810 Low Voltage Supervisory Circuit Features Description
 Precision low voltage monitoring The TPV803/809/810 is a series of supervisory circuit  200 ms (typical) reset timeout that monitors power supply voltage levels and  Open-drain Active-low output (TPV803) provides a power-on reset signal. They provide a reset output during power-up, power-down, and  Push-pull Active-low output (TPV809) brownout conditions.  Push-pull Active-high output (TPV810) The reset timeout periods are fixed at 200 ms (typical).  Low power consumption: 2.2 μA The TPV803 and TPV809 provide an active low reset  Guaranteed reset output valid to VCC = 1 V signal (RESET ), whereas the TPV810 provides an  Power supply glitch immunity active high signal (RESET) output. The TPV809 and  Specified from −40°C to +125°C TPV810 have push-pull outputs, whereas the  3-lead SOT23-3 and SOT23G-3 package TPV803 has an open-drain output, which requires an external pull-up resistor.
Applications
The TPV803/809/810 is available in 3-lead SOT23-3  Microprocessor systems and SOT23G-3 package and typically consumes only 2.2 μA, suitable for use in low power, portable  Computers applications.  Controllers  Intelligent instruments  Portable equipment
