The MAX20305/MAX20306 are overvoltage protectors that provide protection against positive voltages fault up to +28VDC to valuable consumer circuits. An internal clamp also protects the devices from surges up to ±100V. An overcurrent flag can be used to shut down the part.The devices feature reverse-bias-blocking capability. Unlike other overvoltage protectors, when the devices are disabled, the voltage applied to OUT does not feed back into the VBUS side. The devices also feature OTG enable (OTG_EN) that allows OUT voltage to supply VBUS when OUT is higher than output startup voltage.These overvoltage-protection devices feature high voltage, low on-resistance (23mΩ, typ) internal FETs, effectively minimizing a voltage drop across the device. When the input voltage exceeds the overvoltage threshold, the internal FET is turned off to prevent damage to theprotected components. These devices also have thermal shutdown protection against overload conditions.The overvoltage-protection threshold can be adjusted to any voltage between 3.5V and 5.5V with optional external resistors. The devices automatically choose the accurate internal trip thresholds when the overvoltage-lockout input is set lower than the external OVLO select voltage. The internal OVLO is preset to 4.7V (typ).These devices are available in a 30-bump (2.65mm x 2.23mm) wafer-level package (WLP) and operate over the -40°C to +85°C extended temperature range.ApplicationsPhabletsSmart PhonesTablets

The MAX20310 is a compact power managementintegrated 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 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.ApplicationsPortable Medical DevicesWearable Fitness DevicesWearable Medical Devices

The MAX20313–MAX20316 programmable current-limit switches feature internal current limiting to prevent damage to host devices due to faulty load conditions. These current-limit switches feature a low, 10mΩ (typ) on-resistance and operate from a +2.5V to +5.5V input voltage range. The current limit is adjustable from 500mA to 6A, making these devices ideal for charging a large load capacitor and for high-current load-switching applications.The MAX20313 and MAX20315 feature a continuous current-limit mode during an overcurrent event. The MAX20314 and MAX20316 feature a latchoff mode during an overcurrent event. Additional safety features include thermal shutdown protection to prevent overheating and reverse current blocking to prevent current from being driven back into the source.The devices are available in a 12-bump (0.4mm pitch, 1.68mm x 1.48mm) wafer-level package (WLP) and operate over the -40°C to +85°C extended temperature range.ApplicationsData Modem CardsPortable Media PlayersRF Power Amplifiers in Cell PhonesSDXC Card Power Supply ProtectionUSB PortsUTCA/ATCA Platforms
