Product Introduction

R5478N184CJ-TR-FF is a single-cell lithium battery protection chip from Ricoh. It features overcharge detection at 3.65V, over-discharge detection at 2.5V, and over-discharge release at 3.0V. Overcurrent detection is at 0.2V. If using a 8205 MOSFET with a 25mΩ resistance, the overcurrent detection would be 0.2/0.025*2=4A. To increase the overcurrent, use a MOSFET with a lower resistance, such as the 8810, which has a resistance of only 12.5Ω, allowing for an overcurrent of 8A. Some MOSFETs have a resistance as low as 6mΩ, and two combined give 12mΩ, enabling an overcurrent of over 16A. With four MOSFETs, theoretically, a current of 32A can be achieved.

Lithium-iron has seen increasingly widespread applications in recent years, especially in the past two years, where much of it is used for energy storage batteries and solar power generation systems.

This has high requirements for overcurrent protection; on hot summer days, it's prone to overcurrent. This material is very effective for use in the control panels of solar-powered lamps. Welcome all customers to choose it.
