MAX4826–MAX4831

50mA/100mA Current-Limit Switches

with NO-LOAD Flag in µDFN

General Description

Features

The MAX4826–MAX4831 family of switches has internal

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. These

devices are available with guaranteed 50mA and

100mA current limits, making them ideal for load-

switching applications. In addition to the current-limit

fault flag (FFLG), an open-drain no-load flag indicator

(NOLD) notifies the system when the current through

the switch is less than 10mA (MAX4826–MAX4829), or

5mA (MAX4830/MAX4831).

● Guaranteed Current Limit: 50mA, 100mA

● Thermal Shutdown Protection

● Reverse-Current Protection

● 0.7Ω On-Resistance (MAX4826–MAX4831)

● 14ms Guaranteed Blanking Time

● Fault Flag (FFLG)

● No-Load Flag (NOLD)

● 65µA Supply Current

● 8µA Latchoff 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 MAX4826/MAX4828/MAX4830 enter a latchoff state

where the switch is turned off, and FFLG is issued to

the microprocessor. The switch can be turned on again

by cycling the power or ON.

● 0.01µA Shutdown Current

● +2.3V to +5.5V Supply Range

● Undervoltage Lockout

● Fast Current-Limit Response Time

● 6-Pin µDFN Package (1mm x 1.5mm)

The MAX4827/MAX4829/MAX4831 have an autoretry fea-

ture where the switch turns off after the blanking time, and

then continuously checks to see if the overload condition

is present. The current-limit fault flag (FFLG) is issued and

remains low until after the fault condition is removed. The

switch remains on after the overload condition disappears.

Applications

● GPS Systems

● Cell Phones

● Digital Still Cameras

● PDAs and Palmtop Devices

● MP3 Players

The MAX4826–MAX4831 operate over the extended

-40°C to +85°C temperature range, and are available in a

tiny space-saving, 1mm x 1.5mm, 6-pin µDFN package.
