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
• Reset Time-out Delay:
- 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
- TCM811, TCM812
• Fully static design
• Low voltage operation (1.0V)
• ESD protection:
- ≥4 kV Human Body Model (HBM)
- ≥400V Machine Model (MM)
• Extended (E) Temperature range:
-40°C to +125°C
• Package Options:
- 4-lead SOT-143
- 5-lead SOT-23
- Pb-free Device
