DESCRIPTION

The MP5098 is a 12V/5V, low quiescent current

(IQ), low on resistance (RDS(ON)), dual-channel efuse

protection device with current monitoring. It

protects output circuitry from input transients,

as well as protects input circuitry from output

shorts and transients.

At start-up, the inrush current is limited by

limiting the output slew rate. The slew rate is

controlled via the SS pin capacitor (CSS).

The maximum load current (ILOAD_MAX) at the

output is current-limited. The magnitude of the

current limit (ILIMIIT) is fixed internally.

Full protection features include output overvoltage

protection (OVP), over-current

protection (OCP), short-circuit protection (SCP),

and thermal shutdown.

The output voltage (VOUT) is limited by output

OVP. Each rail’s output current (IOUT) can be

monitored via a resistor connected between the

IMON1 and IMON2 pins.

The MP5098 is available in a space-saving

TQFN-10 (2mmx3mm) package.
