# TPS3436BFACADDFRQ1 (Component) ## Description Automotive Nano-Power Precision Window Watchdog Timer – Automotive-grade precision window watchdog timer for automotive ECUs, ADAS, industrial controllers, safety-critical embedded systems, and microcontroller supervision. Operates from a 1.04 V to 6.0 V supply with an ultra-low 250 nA typical quiescent current, making it ideal for always-on and battery-powered applications. Features a programmable precision window watchdog with ±10% timing accuracy, factory-programmed or capacitor-programmable watchdog timeout (1 ms to 100 s), programmable reset delay (2 ms to 10 s), watchdog startup delay, open-window to close-window ratio selection (1× to 511×), manual reset (MR) support, latched or non-latched fault output, and open-drain active-low watchdog output for reliable system monitoring. Qualified to AEC-Q100 Grade 1, it operates over a −40°C to +125°C ambient temperature range and is housed in a compact 8-pin TSOT-23 (DDF) package. #TexasInstruments #TPS3436BFACADDFRQ1 #TPS3436Q1 #WatchdogTimer #WindowWatchdog #SupervisorIC #SystemMonitor #FunctionalSafety #AutomotiveElectronics #AECQ100 #TSOT238 #EmbeddedSystems ## Component Details - **Owner:** silicon-yard - **Created:** 7/27/2026 - **Last Updated:** 7/27/2026 - **Visibility:** Public - **Datasheet URL:** https://storage.googleapis.com/graviton-electric-symbols/document_assets/user-uploaded/8bb1846e113bec4f5972452a07ab0bfd690e56aa1d3cc926386a677efd0460e9.pdf - **Manufacturer Part Number:** TPS3436BFACADDFRQ1 - **Manufacturer Name:** Texas Instruments - **Symbol Style:** parametric-v1 - **Part Type:** Integrated Circuit - **Used in:** 21 projects ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
