Single-Chip BCDMOS Power Switch
The FSDH0165 is a self-biased and protected linear control current-to-duty cycle converter with an open drain output. The device operates from 6.7V to 21V at a frequency of 100KHz. It is equipped with built-in start-up switch eliminating the need for an external start up resistor. Other features include auto-restart to minimize power consumption in standby mode, overload protection, over current protection and internal thermal shutdown protection. The DIPH package enhances thermal conductivity by connecting a single, wide lead to two ground pins. When used in combination with the Fairchild FAN7563 controller IC, the FSDH0165 provides a space saving, two-IC solution for low-power battery charging applications.
