The MAX14720/MAX14750 are compact power-management solutions for space-constrained, battery-powered applications where size and efficiency are critical. Both devices integrate a power switch, a linear regulator, a buck regulator, and a buck-boost regulator. The MAX14720 is designed to be the primary power-management device and is ideal for either non-rechargeable battery (coin-cell, dual alkaline) applications or for rechargeable solutions where the battery is removable and charged separately. The device includes a button monitor and sequencer. The MAX14750 works well as a companion to a charger or PMIC in rechargeable applications. It provides direct pin control of each function and allows greater flexibility for controlling sequencing. The devices include two programmable micro-IQ, high-efficiency switching converters: a buck-boost regulator and a synchronous buck regulator. These regulators feature a burst mode for increased efficiency during light-load operation. The low-dropout linear regulator has a programmable output. It can also operate as a power switch that can disconnect the quiescent load of system peripherals. The devices also include a power switch with battery-monitoring capability. The switch can isolate the battery from all system loads to maximize battery life when not operating. It is also used to isolate the battery-impedance measurements. This switch can operate as a general-purpose load switch as well. The MAX14720 includes a programmable power controller that allows the device to be configured either 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. Both devices also include a multiplexer for monitoring the power inputs and outputs of each function. These devices are available in a 25-bump, 0.4mm pitch, 2.26mm x 2.14mm wafer-level package (WLP) and operate over the -40°C to +85°C extended temperature range.
