Beschreibung
The TS51111 is a fully-integrated synchronous rectifier for wireless charging applications with additional integrated components to minimize system BOM.The TS51111 includes a high efficiency synchronous rectifier to convert the input AC power signal to a DC output level for batterycharging. The device supports both direct battery charging and indirect power applications. Low Rds-on switches minimize power dissipation. High voltage input capability allows for simple and robust secondary side charger implementation. An integrated switchprovides the battery charging path and combined with the rectifier provides back feed protection to the AC inputs. A precharge currentsource is also included for low battery voltage precharge operation. Communication capability is achieved using integrated high voltage switches.The TS51111 includes several additional modules to allow simple integration into wireless power systems. Integrated resistor dividers with zero-current off-mode allow external ADC measurement of PDC, PACKP, USB and thermistor voltages. High voltage switches are included for communication modulation.Power to an external controller is provided through an integrated LDO. The ultra-low quiescent current regulator can supply highoutput currents at low dropout with minimal current draw from the battery.Available in a 45 pin WCSP and 36 pin 6x6 QFN package.
