### **Descriptions:**
- The TPS3800G27DCKRG4 monitors voltage levels and provides a reset signal to microcontrollers or processors when the supply voltage drops below the threshold.
- It features ultra-low power consumption, making it suitable for battery-powered applications.
- The reset output remains asserted for a set delay after the supply voltage rises above the threshold.
### **Features:**
- **Low Power Consumption:** 1.1µA typical quiescent current
- **Wide Operating Voltage Range:** 0.7V to 6.5V
- **Precision Voltage Monitoring:** ±1.5% threshold accuracy
- **Adjustable or Fixed Reset Timeout:** Configurable via external capacitor
- **Small Package Option:** SC-70 (5-pin) for space-constrained designs
- **Industrial Temperature Range:** -40°C to +125°C
- **Push-Pull Output:** No external pull-up resistor required
This device is commonly used in embedded systems, portable electronics, and industrial applications for reliable power-on reset functionality.
