NU1007 is a highly integrated 9V/10W
full-bridge power stage IC optimized for
wireless power transmitter solutions. It
works with transmitter controller
SP3100 to create a high-performance
wireless power transmitter compliant
with WPC 1.2.3 BPP or customized for
any customer-requested solutions. The
device integrates all critical functions,
such as high-efficiency power FETs, low-
EMI FET driver, bootstrap circuit, 2.5V
LDO and lossless current measurement.
The proprietary current-measurement
circuit provides accurate current
