The 5 V threshold is fixed, so the part is a direct fit for any 5 V rail that needs supervision. The 170 ms reset timeout is longer than the 130 ms minimum on the TLV803EA29VDBZR, which can be an advantage when the 5 V rail has a slow ramp or a large output capacitor. The open-drain output lets the reset signal be pulled up to a different voltage (e.g., 3.3 V) if the processor I/O operates at a lower level, without needing a level shifter. The base product number TPS3851 covers the family, and the part is ROHS3 compliant. ## Package and mounting — 8-SON with exposed pad","metaTitle":"TPS3851H50EDRBT – TI Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3851H50EDRBT: Simple Reset/Power-On Reset, 170 ms min reset timeout, 5V threshold, -40°C to 125°C, 8-SON (3x3) package.
