Variable Cells NiMH Battery Charge Control IC, with DT/dt detecting – LS977-NVT  

 

*Function: Multi-cells, NiMH battery charger features (Cells auto-detection)
*Features:
-Noise filter logic design for reducing PCB's noise to meet high accuracy data collection.
-Battery alive function for waking-up long time no use battery, which battery voltage is so low as no battery.
-Charge current is settable (by external Resistor);
 and Pre/ Fast current are automatically adjusted for different battery voltage level.
-Charge full detecting, -deltaV, 0deltaV, DT/dt
-Charge time out protect.
-Charge status indication by dual color LED for Power on/ Charge/ Full/ Defect.
*Working voltage: 4.5V
*Package: MSOP-10
*Application: Universal NiMH battery charger,
                   (Single charger can charge the variable cells battery pack, such as 4 ~ 8 or 6 ~ 12, or 10 ~ 15).
