BQ2013H
Overview
The bq2013H Gas Gauge IC is intended for battery-pack installation to maintain an accurate record of a battery’s available charge. The IC monitors a voltage drop across a sense resistor connected in series between the negative battery terminal and ground to determine charge and discharge activity of the battery.
- Accurate measurement of available charge in rechargeable batteries
- Designed for electric assist bicycles and other applications
- Measures a wide dynamic current range
- Supports NiCd, NiMH or lead acid
- Designed for battery pack inte- gration - 120µA typical standby current (self-discharge estimation mode) - Small size enables imple- mentations in as little as 1 2 square inch of PCB
- Direct drive of LEDs for capacity display
- Automatic charge and selfdischarge compensation using in- ternal temperature sensor
- Simple single-wire serial communications port for subassembly testing
- 16-pin narrow SOIC Gas Gauge IC for PowerAssist Applications
