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.

Features:
• Precision voltage monitor
- 2.63V, 2.93V, 3.08V, 4.38V and 4.63V trip points (Typical)
• Manual Reset input

- Standard: 280 ms (Typical)
- Optional: 2.19 ms, and 35 ms (Typical)
• Power Consumption ≤15 µA max
• No glitches on outputs during power-up
• Active Low Output Options:
- Push-Pull Output and Open-Drain Output
• Active High Output Option:
- Push-Pull Output
• Replacement for (Specification compatible with):
- TC1270, TC1271
