The TPS3808G15DBVR is a micropower, high-accuracy supervisory circuit manufactured by Texas Instruments. It comes in a 5-pin SOT-23 package. Its primary function is to monitor system voltages and assert a reset signal when the monitored voltage drops below a preset threshold, in this case, 1.5V (hence the "G15" in the part number).
The pin functions are typically as follows:
1. VDD: Supply voltage input.
2. GND: Ground reference.
3. RESET: Reset output. This pin asserts a reset signal when the monitored voltage is below the threshold.
4. MR: Manual reset input. A logic low on this pin can trigger a reset.
5. CT: Capacitor timeout. An external capacitor connected to this pin can adjust the reset delay time.
This device is suitable for applications where accurate voltage monitoring and low power consumption are critical, such as in portable and battery-powered equipment.
