ISL81601. High battery discharge current. Backup power supply system.
Hello!I have developed a printed circuit board based on ISL81601 with powerful transistors IQDH29NE2LM5ATMA1 (MOSFET N-CH 25V 75A PG-TSON-8) and a powerful choke IHDM1008BCEV1R2M3A (FIXED IND 1.2UH 80A 0.3 MOHM Unshielded TH).At the input (VIN) of ISL81601, the system voltage (power supply) is 12V and the load is a server.At the output (VOUT) of ISL81601, the Battery is 4S7P (Nominal Voltage 14.8V)My task is to charge the battery (current 2A) and discharge the battery (current up to 50A).Tell me, how to understand, will ISL81601 be able to control IQDH29NE2LM5ATMA1 transistors?I have provided power supply for the internal LDO from the EXTBIAS pin on the board.
Hi korg,
I will get back to you in a while.
