Single cell BUCK chargers BAT FET functionality

Battery Management
1

Hi MPS experts,

I would like to ask that BATTFET of MP2721 can interrupt discharge currents (BATT to SYS flow) too?
I suppose YES, because Output Over-Current Protection (OCP) and Battery Under-Voltage Protection (UVP) has been stated with BATTFET turns off.

In this case I am wonder why there is no discharge protections like OCD, UTD and OTD?
Here you can find a summary of a BMS protections:

Can MPS offer a battery charger chip with full BMS functionality?

Best regards,
Attila

Hi,
BAT FET is monitored for a OCP, and typically your NTC window will cover for under temp/over-temp cases. Your Isys determines how much load should be drawn from the battery whether or not input is present or not.
