Applications
The TC54VN2902ECB713 is well suited for microcontroller reset supervision, ensuring the processor releases reset only after the 2.9 V supply is stable. It also serves battery-powered portable devices where low quiescent current and accurate undervoltage detection protect data integrity. Additionally, it monitors power rails in industrial and consumer electronics to trigger orderly shutdown or alerting logic.

Frequently Asked Questions
What detection threshold does the TC54VN2902ECB713 use and how accurate is it?
The TC54VN2902ECB713 monitors a fixed 2.9 V threshold with a 2% accuracy tolerance, meaning the trip point falls between approximately 2.84 V and 2.96 V. This tight tolerance ensures reliable reset and supervisory behavior across temperature and process variation in battery and regulated-supply designs.
Which microcontroller families are a good fit for TC54VN2902ECB713 as a reset supervisor?
Any microcontroller running from a 2.9 V to 3.3 V regulated rail pairs well with this device. The open-drain active-low output can pull the RESET pin low directly, and with a quiescent current in the low-microamp range and a compact SOT-23 3-pin footprint, it adds minimal board overhead to ARM Cortex-M0, PIC, and AVR designs.
How does the TC54VN2902ECB713 compare to an adjustable supervisory IC for a fixed 2.9 V rail?
Unlike adjustable supervisors that require two external resistors to set the threshold, the TC54VN2902ECB713 integrates the 2.9 V reference internally, saving at least 2 passive components and reducing layout area. The tradeoff is that the threshold is fixed, so it suits designs where 2.9 V is the intended minimum operating voltage and no post-assembly tuning is needed.
