Short-to-battery protection &
integrated protection features

Monolithic Power Systems leads the market with its family of all-in-one smart USB power supplies. By integrating switching regulator, current limit switch, auto protocol detection, and other features, such as frequency spread spectrum, frequency dithering, load shedding, battery short/CC/DD line protection, low drop-out mode, and line drop compensation, users can simplify their USB power design while optimizing performance and solution size.

Supporting USB type A, USB type C, USB Power Delivery (PD), legacy charging protocols BC1.2 (CDP/DCP), 1.2V/1.2V mode, divider mode, and Qualcomm quick charge (QC), MPS solutions can be used for single port, dual port, or multi-port designs in Consumer and Automotive Applications, including charging ports, remote ports, hubs, remote hub, remote clusters, and after-market USB chargers. For non-PD applications, our parts support up to 15W (5V/3A) per port allowing mobile devices to be charged very quickly. For PD applications up to 100W, our solutions with buck/boost converters and controllers operate with wide input voltage (4V -40V) and digital programming capability to program frequency, slew rate, current limit within 50mA resolution and output voltage within 10mV resolution to meet USP PD 3.0 and PPS specs.
