概要
Description
TPS3700DDCR2 is TI’s TPS3700 voltage supervisor/reset IC. It monitors Vcc and generates a reset signal for microcontrollers/MCUs to ensure proper startup and reliable operation during brown-out, power‑down, or glitches. Key points:
- Fixed or selectable reset thresholds (device family options) with a fast, clean reset output.
- Power-on reset with debouncing and a manual reset input for external forcing of a reset.
- Low quiescent current, suitable for battery-powered systems.
- Glitch filtering and robust operation across the device’s operating range.
- DDCR2 denotes a specific packaging/variant (an 8-pin DCR package variant) with its own pinout and threshold options.
Common uses include MCU/SoC supervision, embedded controllers, and other digital circuits requiring deterministic resets during supply fluctuations. For exact threshold values, pin assignments, and package details, consult the TPS3700 datasheet and TI’s packaging guide for the DDCR2 variant.
