ISL1801

ISL1801 sPMIC for Micro Converter Bias and Drivers The ISL1801 is a power management IC (PMIC) optimized for solar array micro converters and other systems operating from a high voltage DC supply. The ISL1801 can be used in buck, boost or buck-boost microconverter topologies in order to maximize the energy harvest from a solar array. In addition to the power stage and main controller, the ISL1801 includes the bias regulators, gate drivers, current sense amplifier and comparators needed for micro converters. The ISL1801 integrates two switching regulators that can be used to generate the driver and the micro-controller (MCU) power supplies. In addition, it has a low offset, low drift amplifier for current sensing, two comparators for overvoltage and overcurrent protection plus a watchdog timer to reset the MCU if necessary. This single IC solution offers high integration and dramatically reduces the total number of components in the microconverter system improving the system reliability...
