For a new BMS project, I would like to ask regarding the 2ED4820-EM:

  1. Can it be used with back-to-back source configuration for bidirectional current control? The current flow will have 2 directions, one for load connection and one when the charger is connected
  2. Can we use one channel as a low-side MOSFET driver? On your site is says that it is possible at the expense of increased current on VBAT (+8mA) but there no any reference design

Thank you

Hi Sako,

This driver can be used in this way and shunt can also be placed on high side.

Hi SaKo,

As I said, it's better to show a schematic for analyze. If you mean the circuit as shown below. It can work for bi-directional current flow.

However, you have to control the low side MOSFET with external circuit. And you have to keep the charge voltage and battery voltage in a suit range.

Also on common source configuration, could the shunt be on high side?
