TPS4810-Q1: TPS4810-Q1: Adding OVLO protection

Part Number: TPS4810-Q1


Tool/software:

Hello, 

We have the following design specifications. 

Input voltage range: 9-80V
UVLO 18V
OVLO 36V
OC trip: 100A
Reverse Voltage Protection - 50V 
Short Circuit Protection 
Fault or PG output

It looks like the TPS4810-Q1 part will be able to meet all of these requirements (with parallel FETs) except the OVLO.

Is it possible simply to add a OVLO to this IC?   
Maybe using the control inputs (INP1/2)

Thanks in advance, 
Nick 

  • Hi Nick,

    Since there is not an OV pin/detection mechanism for this device, it cannot provide overvoltage protection. An external circuit or clamping diode can be used on the pins of concern to ensure the voltage does not exceed the OV level.

    Thanks,
