Overview
The MAX6429NQUR+T is a low-power, single-level battery monitor with internal hysteresis, manufactured by Maxim Integrated. It operates within the MAX6427–MAX6438 family and features a push-pull low-battery output (LBO). The device monitors power-supply voltage and asserts the LBO when the supply drops below a specified threshold. It deasserts the output after a minimum timeout period once the voltage rises above the high threshold, ensuring supply stabilization before enabling system activity. The component is available in an SOT-23-3 package.
Feature Summary
- Provides single low-battery output indication for monitoring battery conditions
- Includes internal hysteresis to prevent output chatter during voltage transitions
- Features a minimum timeout period to ensure supply voltage stability before system enablement
Applications
- Monitoring single lithium-ion cells
- Monitoring multicell alkaline power supplies
- Monitoring NiCd/NiMH power supplies
Procurement Notes
Verify the specific suffix 'NQUR' against official manufacturer documentation to confirm pinout, threshold specifications, and package details. Ensure compatibility with the target application's voltage requirements and logic levels. Confirm RoHS compliance status as indicated in the part designation. Cross-reference ordering information with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component for applications requiring a simple, low-power solution for detecting low-battery conditions in portable devices. Consider the single-output configuration suitable for systems needing basic warning or shutdown signals. Evaluate the SOT-23-3 package size for space-constrained designs. Verify that the factory-trimmed thresholds meet the specific battery chemistry requirements of the design.
Part Context
The MAX6429NQUR+T belongs to the MAX6427–MAX6438 family of low-power battery monitors. This family offers both single and dual-level output options with internal hysteresis. Devices in this series are designed to indicate three battery states: good, weak, or empty. The family supports various battery chemistries and is available in small packages like SOT-23 and SOT-143, making them suitable for portable electronics.
FAQ
What is the function of the timeout period in the MAX6429?
The minimum timeout period ensures that supply voltages have stabilized before power-converter or microprocessor activity is enabled, preventing premature system activation.
How does the MAX6429 handle voltage fluctuations near the threshold?
The device incorporates internal hysteresis to prevent output chatter when the supply voltage fluctuates near the specified low threshold.
