symbol | parameter | test conditions | minimum | typical value | maximum | unit |
VCC | Input power supply voltage | four | five | six | V | |
VFLOAT | Output floating charging voltage | 0℃≤TA≤85℃ | four point one five eight | four point two | four point two four two | V |
ITRIKL | trickle charge current | VBAT＜VTRIKL,RPROG=1.2K | one hundred | one hundred and twenty | one hundred and fifty | mA |
VTRIKL | Trickle charging threshold voltage | RPROG=1K, VBAT increases | two point eight | two point nine | three | V |
VTRHYS | Trickle charging hysteresis voltage | RPROG=1K | sixty | eighty | one hundred | mV |
When the current is less than 3V, it charges with a small current. When the current is greater than 3V, it charges with a current of about 1A. When the current exceeds 4.2V and does not stop, it is called float charging. The charging chip will control the automatic stop of charging. When the charging current is less than 0.1A, it will trigger the stop of charging. If it exceeds 4.2V and is still charging with a large current, it should be noted that the charging chip may be abnormal.
