Frequently Asked Questions
What overcurrent protection does the MAX1558HETB+ provide and how does the autoreset function work?
The MAX1558HETB+ monitors each channel independently and shuts off the output when current exceeds the programmed limit, which can be set between 100 mA and 1.2 A per channel. The autoreset function automatically cycles the output back on after a fault clears, and a dedicated fault flag pin signals the host processor, enabling event logging without active current monitoring firmware.
How does the programmable current limit on the MAX1558HETB+ accommodate both USB 2.0 unit load and high-power port requirements?
An external resistor sets the MAX1558HETB+ current threshold between 100 mA and 1.2 A per channel, covering both the 100 mA USB 2.0 unit load and the 500 mA high-power port specification without hardware redesign. This range lets a single board design serve both low-power USB accessories and high-current peripherals such as portable hard drives by simply changing the resistor value.
For which compact PCB designs does the MAX1558HETB+ 3 mm x 3 mm LFCSP offer a better solution than discrete USB switch components?
The MAX1558HETB+ integrates dual protected USB switch channels operating from 2.7 V to 5.5 V in a 10-pin 3 mm x 3 mm footprint, replacing separate discrete MOSFETs and supervisory ICs needed for two-port switching. This integration is critical in laptop docking stations, embedded single-board computers, and industrial USB hubs where PCB area for dual-port power switching is tightly constrained.
