GENERAL DESCRIPTION
The range of 2.7V to 4.5V input supply voltage is ideal for battery-powered applications, such as portable electronic equipment. The internal linear regulator is selected when a higher supply voltage rail is available in the system. A feedback return ground path switch is also integrated into the device to minimize the quiescent current during the controller shutdown. This feature provides power savings for energy-critical applications. In addition, a built-in timer is available to protect the internal circuit and help dissipate the energy from the external high-voltage storage capacitor.
