General Description
The MAX1562/MAX1562H/MAX1563 single current-
limited switches provide up to 4A to power up to eight
USB ports. They operate from a 4V to 5.5V input
supply and consume only 40A of quiescent current
when operating and only 3A in shutdown.
The MAX1562/MAX1562H/MAX1563s’ autoreset feature
latches the switch off if the output is shorted, thereby
saving system power. When the short is removed, the
switch is reactivated. A fault-blanking feature enables the
circuit to ignore momentary faults, such as those caused
when hot swapping a capacitive load, preventing false
alarms to the host system. Fault blanking also prevents
fault signals from being issued when the device powers
up the load.
The MAX1562/MAX1562H/MAX1563 provide several
safety features to protect the USB port. Built-in thermal-
overload protection turns off the switch when the die
temperature exceeds +160°C. Accurate internal cur-
rent-limiting circuitry protects the input supply against
both overload and short-circuit conditions. An open-
drain fault signal (FAULT) notifies the microprocessor
when a thermal-overload, current-limit, undervoltage
lockout (UVLO), or short-circuit fault occurs.
The MAX1562 has an active-low ON, and the
MAX1562H has an active-high ON enable input. The
MAX1563 has a selectable active-high or active-low
logic-controlled enable. The current limit is pro-
grammed from 1A to 4A using a resistor.
The MAX1562/MAX1562H are available in 8-pin SO
packages and are pin-compatible upgrades to the
MIC2545A/MIC2549A. The MAX1563 provides the
same features and higher current performance in a
smaller 12-pin (4mm x 4mm) Thin QFN package. These
devices operate over an extended temperature range
(-40°C to +85°C). An evaluation kit is available to speed
designs.
