Rev. 1.00 1 March 08, 2018 HT45B0016 Wireless Charger Transmitter’s Power Stage Features • Integrated Low Side NMOS: RDSON=12mΩ @ VCC=5V • Integrated High Side NMOS: RDSON=30mΩ @ VCC=5V • Integrated OCP function with over current trigger point adjustable using an external resistor • Integrated OTP function • Enable pin (EN) controls the output status • Package type: 23-pin QFN General Description The HT45B0016 is a two-in-one power half-bridge chip developed by Holtek for wireless charger applications. The half-bridge power stage with integrated NMOS, can work with the HT66FW2230 or HT66FW2350 to achieve complete wireless charger solutions. The VIN input range is 4.5V~25V covering various wireless charger transmitter types. The HT45B0016 chip can be flexibly used in differenct architectures, a single chip for half- bridge driver LC series resonance and two chips for full-bridge driver LC series resonance. Combined with the HT66FW2230 or HT66FW2350 software arhcitecture, a half-bridge solution can be used for low power applications while a full-bridge solution can be used for medium power applications. The HT45B0016 is supplied in the 23-pin QFN package type. The PCB layout and other important information are provided in the following sections.
