The digital overcurrent scheme requires using an external power switch with integrated
overcurrent detection, such as: LM3526, MIC2526 (2 ports) or LM3544 (4 ports). These
devices are controlled by PSWn_N signals corresponding to each port. In the case of
overcurrent occurrence, these devices will assert OCn_N signals. On OCn_N assertion,
the ISP1760 cuts off the port power by deasserting PSWn_N. The external integrated
power switch will also automatically cut-off the port power in the case of an overcurrent
event, by implementing thermal shutdown. An internal delay filter of 1 ms to 3 ms will
prevent false overcurrent reporting because of in-rush currents when plugging a USB
device.
