MAX1562, MAX1562H, MAX1563 programmable

MAX1562, MAX1562H, MAX1563 programmable 4A USB current limiting switch with automatic reset and fault shielding function Be The MAX1562 / MAX1562H / MAX1563 single-channel current limit provides up to 4A current for driving up to 8 USB ports. They operate from 4V to 5.5V input power, and only 40μA and 3μA are consumed in the normal operation and turn off. The automatic reset feature of the MAX1562 / MAX1562H / MAX1563 can lock the switch in a shutdown state when the output is short-circuitry, reducing system power consumption. When the short-circuit troubleshoot is removed, the switch is turned on. Failure mobilization makes circuitry ignores instantaneous faults, such as transient overcurrent caused by hot insertion-in-capacity loads, preventing errors from the primary system. Fault elimination functions can also prevent the device from issuing a fault signal when powering is applied to the load. MAX1562 / MAX1562H / MAX1563 provide some security features to protect USB ports. The built-in overheating protection turns off the switch in the die temperature exceeding + 160 ° C. Accurate internal current limit circuit protects the input power supply in overcurrent and short-circuit states. Fault Signal (FAULT) emits an alarm to the microprocessor during thermal overload, current limiting, undervoltage lockout (UVLO) or short-circuit fault. The MAX1562 has an / ON signal, and the MAX1562H has high powerful ON enable input. The MAX1563 has an optional high-level effective or low level effective logic control enable. Through a resistor, the current can be programmed in the range of 1A to 4A. The MAX1562 / MAX1562H uses an 8-pin SO package, which is an upgrade product compatible with Mic2545A / MIC2549A Pins. The MAX1563 provides the same functionality and higher current performance, using smaller sizes of 12-pin (4mm x 4mm) thin QFN package. These devices operate in extended industrial grade temperature range (-40 ° C to + 85 ° C). The design process can be accelerated with the evaluation board.
