Working Principle

The MAX16948AGEE/V+T ICs offer a comprehensive set of power management functions controlled by an internal digital state machine. The state machine is responsible for providing fault handling, sequencing and protection functions. This includes control of the switching FETs, balancing of the cells, protection limits and the charging control.

The state machine accepts the following inputs: a supply voltage, inputs from external analog or digital monitors (e.g. MOSFET levels, etc.), logic inputs from other states, and system configuration registers. The state machine also takes into account the requirements of the system, verifies that all constraints are met and initiates corrective action if they are not.

The state machine will also regulate the system’s voltage and current by controlling a switching FET and/or LDO regulators. This is done by modulating the duty cycle of the switching FET and/or adjusting the output voltage of the LDO regulators. This is done autonomously by the state machine in order to ensure the most efficient power delivery to the system.
