LP87524B-Q1: Programming LP87524B-Q1

Part Number: LP87524B-Q1
Other Parts Discussed in Thread: EV2400

Hello everyone,

I want to program this PMIC. Is there any module that I can program it from PC with USB.

Furthermore, I have EV2400 which is used for program to battery management products. Can I program LP87524B-Q1 with this module?


  • Hello,

    It is not possible to reprogram the PMIC and it already comes with factory programmed settings. However, after PMIC is powered up (VIN and NRST high and EN can be still low or high), it is possible to modify certain settings through I2C interface using MCU software. And EV2400 is not useful for this device.



  • Hello again,

    Firstly thanks for your interest.

    You sad that its not programmable but I have read this info from datasheet. It says output voltage of this PMIC is programmable as you can see below.

    How can I program this PMIC? What do you think about this?



    Information From Datasheet:

    Feature Descriptions (continued)
    The following parameters can be programmed via registers:

    • Output voltage
    • Forced-PWM operation
    • Enable and disable delays for regulators and GPIOs controlled by ENx pins

  • Hi,

    It is possible to change certain register settings of the PMIC through I2C interface. Basically you need to setup the I2C interface through your MCU software and change the register settings.. for example: you can change the output voltage settings through I2C interface with the help of MCU software. However, whatever the changes you make through I2C interface gets reset to default settings after supply has been removed. Please refer to the datasheet for all the possible I2C register settings. Datasheet also provides details about I2C bus protocol and I2C slave address for this device is 0x60.
