TPS35CA38GACDDFRQ1 TI Supervisory Circuit | TSOT-23-8 | 4.63V Threshold, Active-Low Open-Drain

Product Overview

The TPS35CA38GACDDFRQ1 is a supervisory circuit (voltage detector) from Texas Instruments, designed for monitoring power supply voltages in automotive and industrial applications. It features a fixed threshold voltage of 4.63V with a precision of ±1.5% over temperature. The device asserts a reset signal when VDD falls below the threshold and maintains it for a minimum of 140ms after VDD rises above the threshold (active-low, open-drain output). Housed in a compact TSOT-23-8 package, it operates over a wide temperature range of -40°C to +125°C, making it suitable for harsh environments.
