Key Features
- Fixed 2.7 V threshold voltage detection with no external components required, minimizing BOM count in battery-powered designs
- Ultra-compact 3-pin SOT-23A package occupying minimal PCB area for tight space-constrained portable and wearable designs
- Single-channel voltage supervisor with open-drain reset output for direct connection to MCU reset pins in 3.3 V and 2.7 V systems
Applications
The TC54VC2702ECB713 is used to supervise power rails in battery-operated portable devices, microcontroller systems, and IoT sensor nodes where the supply must stay above 2.7 V for reliable operation. It asserts a reset or interrupt signal when the monitored rail drops below its 2.7 V threshold, preventing microcontrollers from executing code in an under-voltage condition that could corrupt memory or cause undefined behavior. Its tiny 3-pin SOT-23A package makes it ideal for wearable electronics, smart metering, and compact industrial sensors with limited board space.

Frequently Asked Questions
At what supply voltage does the TC54VC2702ECB713 assert its reset output, and how precise is that threshold?
The TC54VC2702ECB713 asserts its reset output when the monitored supply falls below 2.7 V. Microchip specifies the threshold accuracy at ±2%, meaning the detection window is between approximately 2.65 V and 2.75 V. This tight accuracy prevents nuisance resets in 3 V lithium-coin-cell systems where the end-of-life voltage approaches 2.7 V.
How does the fixed-threshold design of TC54VC2702ECB713 simplify the reset circuit compared to adjustable supervisors?
Because the 2.7 V threshold is factory-trimmed, the TC54VC2702ECB713 requires no external resistor divider, capacitors, or trim potentiometers. The designer connects only 3 pins: supply, ground, and reset output. This reduces the component count by 2 to 3 parts per channel and eliminates resistor tolerance errors that can shift the trip point in adjustable designs.
Which battery chemistries pair well with the 2.7 V monitoring threshold of TC54VC2702ECB713?
The 2.7 V threshold aligns closely with the end-of-discharge voltage of lithium primary cells (typically 2.7 V to 3.0 V) and LiFePO4 cells (2.5 V cutoff). It also suits 2-cell alkaline or NiMH packs, which drop below 2.7 V when nearly depleted. Using TC54VC2702ECB713 on these chemistries gives the MCU a reliable low-battery shutdown signal before harmful deep discharge occurs.
