Accurate Measurement: Based on the LTC4150, this module precisely measures both battery charging and discharging by monitoring current through an external sense resistor, enabling reliable coulomb counting for battery-powered devices.
Pulse Output: Converts measured current into pulse signals on the interrupt output pin, where pulse count represents total charge and pulse polarity indicates charge or discharge direction, simplifying MCU integration and data logging.
Wide Voltage Detection: Supports detection voltages from 2.7V to 8.5V, with a maximum detection current up to 1A, making it suitable for single-cell and multi-cell portable battery systems.
Logic Level Compatibility: Operates with both 3.3V and 5V logic levels, allowing direct connection to common microcontrollers.
Portable Applications: Small 30 x 15mm form factor designed for space-constrained designs, ideal for handheld devices, portable electronics, battery monitoring projects, and power management development.
