General Description

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 sys-

tem power management features like a push-button monitor

and sequencing controller.

The device includes a SIMO buck-boost switching regula-

tor 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.

All devices are 100% production tested at T

A

= +25°C. Limits over the operating temperature range are guaranteed by design.

V

BAT

refers to the voltage across the battery terminals; V

BAT

= V

GND

– V

BATN

.

Output voltage must not exceed V

BB_OUT

- V

BATN

= 5.0V.

Actual value may be limited by the lower of the capability of the source (battery) or the maximum input power of the MAX20310.

Timing must be fast enough to prevent the device from entering sleep mode due to bus low for period > t

SLEEP

.

f

SCL

must meet the minimum clock low time plus the rise/fall times.

The maximum t

HD:DAT

has to be met only if the device does not stretch the low period (t

LOW

) of the SCL signal.

The device internally provides a hold time of at least 100ns for the SDA signal (referred to the V

IH_MIN

of the SCL signal) to

bridge the undefined region of the falling edge of SCL.
