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