These parts are in production but have been determined to be NOT FOR NEW DESIGN. This classification indicates that sale of this device is currently restricted to existing customer applications. The device should not be purchased for new design applications because obsolescence in the near future is \n• 600 kHz to 2.2 MHz switching frequency—ability to operate above the AM band \n• Internal bias supply for single-supply operation (VIN = 8 to 21 V) \n• Boost converter with integrated 40 V DMOS switch and OVP—load-dump protection \n• 3.5 µA shutdown current—limits battery drain \n• Active current;
