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.
