The Texas Instruments TPS3123J12DBVR is an ultra-low voltage processor supervisory circuit. It monitors a single supply rail and asserts a RESET output when the voltage drops below a threshold. This device features a manual reset input and a watchdog timer that can retrigger the RESET output.
Key electrical specifications include a typical threshold voltage of 1.2V and 1.8V, with a reset threshold accuracy of 3.7%. The typical supply current is a low 0.014mA. The reset output is active-low and push-pull, with a fixed time delay of 180ms. The watchdog timer has a typical timeout of 1.4 seconds.
This supervisor IC is housed in a compact SOT-23-5 package, suitable for surface mounting. It operates over a temperature range of -40°C to 85°C. The minimum supply voltage is 0.9V, and the supervision range includes 1.2V, 1.5V, and 1.8V options.
Designed for applications requiring reliable power-on reset and voltage monitoring, the TPS3123J12DBVR is ideal for embedded systems and microcontrollers where maintaining system stability is critical.
