Pin Functions

PIN I/O DESCRIPTION
NO. NAME
1 VCC I Power supply input.
2 MR I Manual-reset input. When MR is less than VMRT (manual reset threshold) RESET/RESET is engaged.
3 PFI I Power-fail comparator input. When PFI is less than VPFT (power-fail reset threshold), the PFO goes low. Otherwise, PFO remains high.
4 NC — No connection.
5 GND — Ground reference for all signals.
6 NC — No connection.
7 LLO O Low-line logic output. Early power-fail warning output. Low when VCC falls below VLLOT (low-line output threshold). This output can be used to generate an NMI (non-maskable interrupt) to provide an early warning of imminent power failure.
8 PFO O Power-fail logic output. When PFI is below VPFT, PFO goes low; otherwise, PFO remains high.
9 NC — No connection. Test input used at factory only. Leave floating.
10 RESET O Reset logic output. Pulses low for tRP (reset time-out period) when triggered, and stays low whenever VCC is below the reset threshold or when MR is below VMRT. It remains low for tRP after either VCC rises above the reset threshold, or after MR input rises above VMRT.
