The bq25046 is a highly integrated linear power supply IC targeted at both wired and wireless power applications. With an accurate 5-V regulated output and integrated 3.3-V LDO, the bq25046 is an ideal solution for wireless power supply solutions up to 5 W.
The bq25046 integrates several functions which enable a wireless charging solution within a small area and low component count. These include a 3.3-V LDO which drives an MSP430BQ1010 wireless controller, high-accuracy current sense for calculating receiver-side power usage, 100mA/400mA current limits enable robust communication at all load current levels, and integrated pass FET acts as load disconnect switch and 5-V regulator to protect downstream circuitry. In addition, the bq25046 has an absolute maximum input voltage of 30 V and an OVP threshold of 15 V, which enables safe and robust operation in inductive power transfer systems that use either resistive or capacitive load modulation.
