Power Management ICs (PMICs) typically control and interface communication with a host system along with power distribution to the various systems within an electronic device. PMICs allow the device to reach its maximum efficiency level while consuming the minimal amount of power. One type of PMIC is motor driver controllers, which are integrated circuits used to enable proper communication and control over a motor. The BTN7970PAKSA1 is one such motor driver controller, designed to provide superior performance and control in embedded motor applications.
