Texas Instruments TPS343xEVM Evaluation Modules (EVMs)

Texas Instruments TPS343xEVM Evaluation Modules (EVMs) are platforms for evaluating the TP3430 or TPS3431 device. TPS3430 is a standalone window watchdog timer with a programmable window watchdog and programmable reset delay, and the TPS3431 is a standard programmable watchdog timer with an enabling feature. Both devices are designed for a wide variety of applications. Each device is used to monitor watchdog input from an MCU and trigger the watchdog output if no pulse arrives within the programmed watchdog window. The TPS3430 is programmable by configuring SET0 and SET1 pins and by changing the capacitor on CRST and CWD. On the TPS3431, the watchdog timeout and delay can be programmed with a capacitor on the CWD pin. The TPS3431 also features a watchdog disabled with the SET1 and/or EN pins.
