50mA/100mA Current-Limit Switches

General Description

Features

♦ Guaranteed Current Limit: 50mA, 100mA

The MAX4785–MAX4788 family of switches feature inter-

nal current limiting to prevent host devices from being

damaged due to faulty load conditions. These analog

switches have a low 0.7Ω on-resistance and operate

from a 2.3V to 5.5V input voltage range. They are avail-

able with guaranteed 50mA and 100mA current limits,

making them ideal for load-switching applications.

♦ Thermal-Shutdown Protection

♦ Reverse-Current Protection

♦ 0.7Ω On-Resistance

♦ 14ms Guaranteed Blanking Time

♦ FLAG Function (MAX4785/MAX4787)

♦ 65µA Supply Current

When the switch is on and a load is connected to the

port, a guaranteed blanking time of 14ms ensures that

the transient voltages settle down. If after this blanking

time the load current is greater than the current limit,

the MAX4785 and MAX4787 enter a latch-off state

where the switch is turned off and FLAG is issued to the

microprocessor. The switch can be turned on again by

cycling the power or the ON pin.

♦ 8µA Latch-Off Current (MAX4785/MAX4787)

♦ 0.01µA Shutdown Current

♦ 2.3V to 5.5V Supply Range

♦ Undervoltage Lockout

The MAX4786 and MAX4788 have an autoretry feature

where the switch turns off after the blanking time and

then continuously checks to see if the overload condi-

tion is present. The switch remains on after the overload

condition disappears.

♦ Fast Current-Limit Response Time

♦ Tiny SC70 Package

Ordering Information

The MAX4785 and MAX4787 are available in a tiny

space-saving 4-pin or 5-pin SC70 package. The

MAX4786 and MAX4788 are available only in the 4-pin

SC70 package. For higher current current-limiting

switches, refer to the MAX4789–MAX4794 and

MAX1693 data sheets.
