Overview
The MAX6775LTB+ is a low-power, single-cell battery monitor from the MAX6775 series. It provides a 1%-accurate threshold for detecting low-battery conditions in lithium-ion or multicell alkaline/NiCd/NiMH sources. The device features an open-drain or push-pull output with fixed or resistor-adjustable hysteresis to eliminate chatter. It operates from -40°C to +85°C and draws only 3µA of battery current. Packaged in a compact SC-70-5 (SOT-323) surface-mount case, it ensures valid logic states down to 1V input.
Feature Summary
- Provides 1%-accurate low-battery detection over temperature
- Features fixed or resistor-adjustable hysteresis to prevent output chatter
- Offers open-drain or push-pull output options
- Operates with ultra-low 3µA battery current consumption
Applications
- Single lithium-ion cell monitoring
- Multicell alkaline power source supervision
- NiCd/NiMH battery pack management
- Portable electronic devices requiring low quiescent current
Procurement Notes
Verify component authenticity through authorized channels due to limited supply status. Confirm package marking matches SC-70-5 specifications. Check datasheet revision for electrical parameter updates. Ensure storage conditions comply with moisture sensitivity level requirements before reflow soldering.
Selection Notes
Select this part when precise 1% accuracy is critical for battery cutoff. Choose between open-drain or push-pull outputs based on system interface needs. Utilize adjustable hysteresis if input noise is present. Verify that the SC-70-5 footprint fits the PCB layout constraints.
Part Context
Part of the MAX6775–MAX6781 family of low-power battery monitors. Shares core functionality with variants offering dual outputs or different packages like µDFN. Designed for applications where space and power efficiency are primary design drivers.
Replacement Considerations
Consider MAX6775LTA+ for identical function in alternative packaging. Verify pinout compatibility when substituting with other MAX677x series members. Ensure hysteresis configuration remains consistent during replacement.
FAQ
What is the minimum operating voltage for valid logic output?
The device guarantees a valid low-battery-output logic state down to VBATT = 1V.
How does the device handle input voltage noise?
It features fixed or resistor-adjustable hysteresis to eliminate output chatter caused by input-voltage noise or terminal voltage recovery.
