Abstract: A current limiting MOSFET monitors power applied to a direct current boost regulator that powers an LED backlight to automatically shut off power to the boost regulator if the current exceeds a predetermined amount. An embedded controller interfaces with the current limiting MOSFET for normal control of operation of the boost regulator by turning the MOSFET on and off. An overcurrent alert is communicated from the MOSFET to the embedded controller if the current exceeds the predetermined amount so that the embedded controller shuts off power to the boost regulator and indicates the failure to an end user.

Abstract: A charger provides a charging current to an information handling system battery by measuring current provided from an external power source using a Hall sensor. The Hall sensor is integrated into an integrated circuit of the charger to measure current provided by an external power source and output a voltage proportional to the measured current. The charger analyzes the external power source current relative to an available current to determine the charging current. The Hall sensor provides the total current from the charger with minimal resistance to reduce power consumption at the charger.

Abstract: An information handling system that includes a processor, a memory, a program, a battery, and a module. The module receives a request for first information associated with the battery from the program, accesses the first information, converts the first information into second information, and provides the second information to the program in response to the request.
