Product Details

The MAX20310 is a compact power management integrated circuit (PMIC) for space-constrained, battery-powered applications where size and efficiency are critical. The device combines two single inductor, multiple output (SIMO) buck-boosted outputs with two LDOs and other system power management features like a push-button monitor and sequencing controller.

The device includes a SIMO buck-boost switching regulator that provides two programmable voltage rails using a single inductor, minimizing solution footprint. The MAX20310 operates with battery voltages down to 0.7V for use with Zinc Air, Silver Oxide, or Alkaline batteries. The architecture allows for output voltages above or below the battery voltage.

Additionally, the MAX20310 has two programmable low-dropout (LDO) linear regulators. The linear regulators can also operate as power switches that can disconnect the quiescent load of system peripherals.

The MAX20310 includes a programmable power controller that allows the device to be configured for use in applications that require a true off state or for always-on applications. This controller provides a delayed reset signal, voltage sequencing, and customized button timing for on/off control and recovery hard reset.

The device also features a multiplexer for monitoring the power inputs and outputs of each function. The MAX20310 is available in a 16-bump 0.4mm pitch 1.63mm x 1.63mm wafer-level package (WLP) and operates over the -40°C to +85°C extended temperature range.
