VSS — Power Ground
— — RST O Push- Reset output (Push Pull), active low
Pull H = VDD > VTRIP, Reset pin is inactive
(after Reset Timer Delay completes)
L = VDD < VTRIP, Reset pin is active
Goes active (Low) if one of these conditions
occurs:
1. If VDD falls below the selected Reset
voltage threshold.
2. If the MR pin is forced low.
3. During power-up.

2 RST O Push- Reset output (Push Pull), active high
Pull H = VDD < VTRIP, Reset pin is active
L = VDD > VTRIP, Reset pin is inactive
(after Reset Timer Delay completes)
Note 1:
Goes active (High) if one of these conditions
occurs:
1. If VDD falls below the selected Reset
voltage threshold.
2. If the MR pin is forced low.
3. During power-up.
The MR pin has an internal weak pull-up (18.5 kΩ typical).

General Description
For many of today’s microcontroller applications, care must be taken to prevent low-power conditions that can
cause many different system problems. The most common causes are brown-out conditions, where the system supply drops below the operating level momentarily. The second most common cause is when a slowly decaying power supply causes the microcontroller to begin executing instructions without sufficient voltage to sustain volatile memory (RAM), thus producing indeterminate results.
