ACT81460 Low Power PMIC With Integrated Linear Charger BENEFITS and FEATURES APPLICATIONS Wide Input Voltage Range Consumer or medical wearables. 4V to 5.5V Input with 20V Protection Battery operated personal devices. 2.7V to 4.5V Battery Range IOT Modules. Cameras & DVRs Complete Integrated Power Solution Two 0.4A DC/DC Step-Down (Buck) Regulators One 0.4A Buck-Boost Regulator GENERAL DESCRIPTION Three 100mA LDOs The ACT81460 is a low power PMIC (power Three 100mA Load Switches management integrated circuit) that is specifically One High Voltage Boost 20V designed for battery operated systems and is suitable 38mA Constant Current Sink LED Drive for a variety of processor applications. It features very 0.8A Linear Charger low standby current that prolongs battery life between charges, especially in applications requiring long stand Optimized Power for Portable Applications by or low power mode durations. It is a highly efficient Active Power-Path Linear Charger (APLC) PMIC that also enhances battery run time during normal Multiple Sleep Modes operating modes. The number of regulators that can be Active-COT for Very Low Quiescent Current turned OFF or left ON during low power modes is 6A Quiescent Current with 6 regulators and 3 configurable and offers users flexibility to optimize load switches running system efficiency. Space Savings The IC includes four DC/DC converters with integrated Fully Integrated power FETs, three low-dropout regulators (LDOs), and three load switches. Two of the DC/DC converters are Maximum Fsw = 3MHz for small size step down buck regulators, one is a step up/down buck- Integrated Sequencing boost regulator and the fourth is a high voltage step-up Easy System Level Design boost regulator capable of providing up to 20V. Each Configurable Sequencing regulator can be configured for a wide range of output 2 voltages through the I C interface. Seamless Sequencing with External Supplies Programmable Reset and Power Good GPIOs The ACT81460 is highly configurable. It offers configurable power sequencing combinations, startup Easy System Interface and Monitoring timing, output voltage settings, fault monitoring, Four General Purpose I/O (4 X GPIOs) interrupt control, programmable GPIO options, and I2C Serial Interface many more features. The device is pre-configured at the Reset and Power Sequencing Control factory with default configuration settings that can be Interrupt Controller and fault monitoring 2 further adjusted though firmware via the standard I C Two configurable low power modes SLEEP & interface to suit individual system requirements. The IC DPSLP mode. also features the ability to sequence external power Watchdog Supervision supply rails as part of the power up sequence by using GPIOs.
