The MAX14746/MAX14747 are a series of USB charger detectors with an integrated Smart Power Selector™ linear charger solutions that provide a single-chip solution for charging and charger detection.The MAX14746/MAX14747 charger detectors are compliant to USB Battery Charger Detection Rev 1.2* and capable of detecting multiple USB battery-charging methods, including Standard Downstream Ports (SDP), Charging Downstream Ports (CDP), and Dedicated Charger Ports (DCP). The devices also detect common proprietary charge adapters, including those from Apple.The MAX14746/MAX14747 battery chargers feature Smart Power Selector operation, allowing operation with dead or no battery present. The devices limits USB VBUScurrent based on the detect charger source type. If the charger power source is unable to supply the entire system load, the smart-power control circuit supplements the system load with current from the battery.The devices protect against overvoltage faults up to 28V.This series of USB charger detectors are available with several options, with slight variations in, for example, power-up states. These variations are noted throughout this data sheet.There are five options available with slight variations in, for example, power-up states. The devices are available in a 25-ball, 0.4mm pitch wafer-level package (WLP), and are specified over the -40°C to +85°C extended temperature range.ApplicationsPortable Consumer DevicesPortable Digital CamerasPortable Digital Video CamerasPortable Industrial Devices

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.Design Solution: How to Add ECG to Your Wearable Without Raising Your Heart Rate ›ApplicationsPortable Medical DevicesWearable Fitness DevicesWearable Medical Devices

The MAX14752/MAX14753 are 8-to-1 and dual 4-to-1 high-voltage analog multiplexers. Both devices feature 60Ω (typ) on-resistance with 0.03Ω (typ) on-resistance flatness. These low on-resistance multiplexers conduct equally well in either direction. Flexible logic levels for the channel-select interface are defined by the EN input.The MAX14752 is a 8-to-1 multiplexer and MAX14753 is a dual 4-to-1 multiplexer. Both devices operate with dual supplies of ±10V to ±36V, or a single supply of +20V to +72V.The MAX14752/MAX14753 are available in a 16-pin TSSOP package and are pin compatible with the industry-standard DG408/DG409. Both the MAX14752/MAX14753 are specified over the extended -40°C to +85°C operating temperature range.ApplicationsATE SystemsEnvironment Control SystemsMedical Monitoring SystemsProgrammable-Logic Controllers

The MAX14759/MAX14761/MAX14763 analog switches are capable of passing bipolar signals that are beyond their supply rails. These devices operate from a single +3.0V to +5.5V supply and support signals in the -25V to +25V range.The MAX14759 is a single-pole/single-throw (SPST) analog switch, while the MAX14761 is a dual-SPST analog switch. The MAX14763 is a single-pole/double-throw (SPDT) analog switch.The MAX14759 features 1Ω (max) on-resistance with a ±200nA (max) on-leakage current. The MAX14761/MAX14763 feature 2Ω (max) on-resistance with a ±100nA (max) on-leakage current. The low on-resistance and high bandwidth allow use in digital- and analog-signal switching applications.The MAX14759/MAX14763 are available in an 8-pin (3mm x 3mm) TDFN package. The MAX14761 is available in a 10-pin (3mm x 3mm) TDFN package.
