The Texas Instruments TPS3514DR is a 3-channel supervisor integrated circuit suitable for switch-mode power supply applications. This device monitors multiple voltage rails, including 3.3V, 5V, and 12V, providing essential protection features.
Key specifications include overcurrent detection and lockout for 12V, 5V, and 3.3V supplies, as well as undervoltage protection for 12V and undervoltage detection for 5V and 3.3V supplies. It also incorporates overvoltage protection and lockout for these voltage levels. The supervisor features an active-low, open-drain reset output with a typical time delay of 300ms. It also includes a power-good output signal for 3.3V and 5V supplies with a 300ms delay.
The TPS3514DR operates within a temperature range of -40°C to 85°C. It is available in a 14-SOIC package, designed for surface mount applications. The part also includes power-supply short-circuit turn-on protection and PSON control to FPO turn-off functionality.
This product is not recommended for new designs. Existing customers can continue to use it, but new designs should consider alternate products.
