The MAX8688BHETG+ is a power supply controller and monitor integrated circuit manufactured by Maxim Integrated Products. It is designed to provide a cost-effective and reliable solution to meet the requirements of portable and low-power systems. The MAX8688BHETG+ provides the features necessary to manage and monitor power delivery of portable power supplies with Rail-to-Rail Input and Output (RT-IO) capability.The MAX8688BHETG+ operates in two modes: output voltage mode and current-limit mode. In output voltage mode, the MAX8688BHETG+ operates as a fixed-output, low-power mode regulator. Output voltage and current are set by external resistors and a current-limit can be set using an internal resistor. The device also includes a low-battery detector and a sleep output, which can be used to control a system in a low-power state.In current-limit mode, the MAX8688BHETG+ operates as an adjustable-output, current-limited linear regulator. The output voltage is set by an external resistor, and the output current is limited by an internal reference voltage and a current-limit resistor. The device also includes a power-on reset controller and a low-battery detector.The MAX8688BHETG+ features an optimized power architectures and thermal-management features, which guard against thermal runaway and enable a wide operating range. In addition, the device supports a wide range of programmable features including slew rate control, pull-down resistors, and polarity reversal. The MAX8688BHETG+ is ideal for powering low-voltage logic and low-power LED applications such as portable and embedded systems, mobile phones, lid-mounted notebook computers, and device charging.The MAX8688BHETG+ is available in a 16-pin, 4mm x 4mm QFN package. It operates from a single +2.7V to +5.5V input supply and is specified for operation over a wide temperature range from -40°C to +125°C.
