The SGM260421 is a highly-integrated multi-channel power management circuit. It supports a variety of microcontrollers and solid-state drive applications. It incorporates four Bucks and two LDOs that deliver several output voltages. Buck1 and two LDOs can be set as a load switch while Buck4 can be set as an LDO. The device has several default configurations which are programmed in the factory. Startup sequencing, turn-on delay, extra delay, turn-off delay, wake-up delay, voltage of each channel, soft-start time, SLEEP or DPSLP state, operating modes, and other settings can all be configured.
SGM260421 supplies 8 configurable GPIOs for system hardware control requirements. These GPIOs can be programmed for a variety of functions, including nIRQ, SYSMON, SYSWARN, EXT_EN, I2C controlled output, PG of internal rail, SLEEP/PWREN, PWRDIS, EN of internal rail. Otherwise, GPIO2 - GPIO4 can support three-state status for configuring the default output voltage, regulators operation mode, and extra turn-on delay times.
The SGM260421 is available in Green WLCSP-2.69×2.69-36B, FOCSP-3.35×3.1-34B and TBGA-3.35×3.1-34B packages.
