UT01VS50D - Aeroflex Circuit Technology

UT01VS50D Voltage Supervisor

Number 1 2 3 4 5 6 7 Pins MR VDD GND PFI PFO WDI RESET_OD Type Digital Input TTL/CMOS compatible Supply Supply Analog Input Digital Output Digital Input Open Drain Digital Output Description Manual Reset Input with an internal pull-up. Active low. MR low forces the reset output RESET_OD low. Required minimum MR pulse width is 150ns. RESET_OD is held low.
