Introduction

MoLi3004 is a protection IC designed for 3~4 S lithium-ion batteries. By integrating high-precision voltage, current, and temperature detection with delay circuits, it provides comprehensive battery protection, ensuring safe operation and extending battery service life.

Features

• Charge overvoltage protection: range 【3.650V; 3.850V; 4.150V ~ 4.400V】, accuracy ±25mV, step 25mV, hysteresis 【0 ~ 400mV】, step 100mV
• Discharge undervoltage protection: range 【2.200V ~ 2.800V】, accuracy ±30mV, step 100mV, hysteresis 【200mV ~ 500mV】, step 100mV
• Discharge overcurrent protection:
  • Discharge overcurrent detection 1: range 【0.050V ~ 0.100V】, accuracy ±5mV, step 50mV
  • Discharge overcurrent detection 2: range 【0.100V ~ 0.200V】, accuracy ±10mV, step 100mV
  • Short-circuit protection detection: range 【200mV; 400mV】, accuracy ±20mV
• Temperature protection: four temperature protection thresholds — charge high temperature, charge low temperature, discharge high temperature, and discharge low temperature — flexibly set via external resistors
• Delay time: discharge overcurrent 1, discharge overcurrent 2, and discharge undervoltage delay times flexibly set via external capacitors
• Cell balancing: internal and external balancing to extend battery pack lifespan
• Low-voltage charge inhibit: prevents battery pack abuse and ensures safety
• Status detection: precise charge/discharge status detection for fine-grained protection
• MOS protection: suppresses overheating of charge/discharge MOSFET body diodes for high reliability
• Sleep function: normal state (typical) 15uA, sleep state (typical) 5uA
• Package: SSOP16
