General Descriptions

MT6358 is a power management system chip optimized for IoT devices, containing 9 buck converters and 33 LDOs optimized for specific IoT device subsystems.

Sophisticated controls are available for power-up and the RTC alarm. MT6358 is optimized for maximum battery life, allowing the RTC circuit to stay alive without a battery for several hours.

MT6358 adopts SPI interface and two SRCLKEN control pins to control buck converters, LDOs, and various drivers; it provides enhanced safety control and protocol for handshaking with baseband.

MT6358 is available in a 194-pin MIFO WLCSP package. The operating temperature ranges from -30 to +85°C.
