TPS3851G18SDRBT TI Supervisory Circuits | 8-SON(3x3) | 1.8V Threshold, Watchdog Timer

Product Overview

The TPS3851G18SDRBT from Texas Instruments is a high-accuracy voltage supervisor and watchdog timer designed for reliable system monitoring. It features a fixed 1.8V threshold voltage with ±1% accuracy over temperature, ensuring precise reset generation. The device integrates a programmable watchdog timer with a 1.6s timeout period, making it ideal for safety-critical applications. Housed in a compact 8-SON (3x3 mm) package, it offers low power consumption (typical 5 µA) and operates over a wide temperature range of -40°C to +125°C.
