The TPS3307-18DR from Texas Instruments is a micropower supply voltage supervisor designed for circuit initialization in DSP and processor-based systems. This device features three monitored voltage supplies, with selectable threshold voltages including 1.68V, 2.93V, and an adjustable option. It provides a fixed power-on reset delay time of 200ms, eliminating the need for external capacitors.
The supervisor IC offers both active-high and active-low reset outputs with a push-pull driver type. It operates over a wide temperature range of -40°C to 85°C and requires a supply voltage between 2V and 6V. The defined RESET output is active from VDD ≥ 1.1V. The TPS3307-18DR is available in an 8-SOIC package, suitable for surface mount applications.
Key electrical characteristics include a reset threshold accuracy of 3.2% and a low quiescent current of typically 0.04mA. The device also features complementary outputs, manual reset capability, separate VDD and sense pins, and undervoltage monitoring. It does not include a watchdog timer.
This supervisor is designed for applications requiring reliable power-on reset and voltage monitoring. Its compact 8-SOIC package and robust performance make it suitable for various embedded systems.
