DESCRIPTION
FEATURES
The MP6219 is a protection device designed to
protect circuitry on the output from transients on
input. It also protects input from undesired shorts
and transients coming from the output.

The MP6219 is an integrated power switch with
programmable current limit. The max load at the
output is current limited. This is accomplished by
utilizing a sense FET topology. The magnitude of
the current limit is controlled by an external
resistor.
An internal charge pump drives the gate of the
power device. It features a 44mΩ switch for high
efficiency and requires minimal external
components.
The MP6219 features current protection and
thermal shutdown for fault control. It also involves
UVLO and output over voltage protection.

Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature TJ(MAX), the junction-toambient thermal resistance θJA, and the ambient temperature
TA. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by PD(MAX)=(TJ(MAX)TA)/ θJA. Exceeding the maximum allowable power dissipation
will cause excessive die temperature, and the regulator will go
into thermal shutdown. Internal thermal shutdown circuitry
protects the device from permanent damage.
3) Measured on JESD51-7 4-layer board.
