Battery management chip R5478N203CK-TR-FF

R5478N203CK-TR-FF: Battery management chip. Company advantage inventory.

The 5475N/R5478Nxxxxx series are CMOS based high voltage protection ICs for overcharge/overdischarge.

Rechargeable single-cell Li-Ion (Li+)/Li-Polymer overload current, also includes short circuit

Protector to prevent large external short-circuit current and excessive discharge current.

These ICs all consist of three voltage detectors, a reference unit, a delay circuit, a short circuit

Protectors, oscillators, counters and logic circuits. When the overcharge voltage exceeds the detector

The threshold goes from low to high, after an internal fixed delay, the output of the COUT pin switches to a low level

time. The conditions for releasing the overcharge detector vary by mask option. The so-called "latch"

function" version, after detecting overcharge, the detector can be reset and the output of COUT becomes "H"

After the charger is disconnected from the pack and battery, when a load is connected to VDD

The voltage is below the overcharge detector threshold. If you continue to connect the charger to

The battery pack is not overcharged even if the battery voltage is below the overcharge detector threshold

freed. On the other hand, after detecting "

Overcharge, when the battery voltage reaches the overcharge release voltage, the output of COUT becomes

"H"

The output of the DOUT pin, the output of the overdischarge detector and the overdischarge current detector,

After an internally fixed delay time, when the discharge voltage exceeds the detector threshold, switch to the "L" level

From a higher value to a value less than VDET2.

The conditions for releasing the overdischarge detector also vary by mask option. So-called

"Latch function" version, after detecting overdischarge voltage, connect the charger to the battery pack, then

When the battery supply voltage is higher than the overdischarge detector threshold, VD2 is released,

The voltage of the DOUT pin becomes "H" level. On the other hand, in terms of so-called "release by voltage level"

version, if the charger is not connected, when the battery voltages become equal, the

Overdischarge, the overdischarge detector is released. If the charger and battery are connected

The voltage becomes the voltage released by the overdischarge, and the overdischarge detector is released.

Excessive discharge current and short-circuit conditions can be detected and cut off by built-in excess current

Current detector VD3, DOUT is enabled low. Once an excessive discharge current is detected or

In the event of a short circuit, by removing the battery pack from the load, VD3 is released and the DOUT level is switched high

system.

After overdischarge is detected, the supply current is kept extremely low by stopping the operation of the internal circuit.

When the output of COUT is "H", if the V- pin level is set to Vss-2V, the delay time of the detector can be shortened.

In particular, the delay time of the overcharge detector can be reduced to about 1/57. Therefore, test

The time to protect the circuit board can be reduced. The output type of COUT and DOUT is CMOS. 6-pin, SOT-23-6 is available.
