有关 ISL1801 的资源
描述
Support is limited to customers who have already adopted these products.
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 and reducing cost. The first regulator takes input voltages ranging from 9V to 90V from the solar panel and outputs a regulated supply for drivers and the secondary regulator. The secondary regulator converts the output of the first regulator to a programmable micro-controller supply, typically 3. 3V. A high voltage start-up LDO provides the necessary bias voltage until the switching regulator is operating. The ISL1801 integrates two high-speed MOSFET drivers for buck, flyback or boost converters configured as shown in the application schematics. The Drive3 also has the integrated peak current limiting capabilities. The ISL1801 includes comprehensive start-up, shutdown and fault logic to ensure reliable operation of micro converters in solar applications.
