RT9712

90mΩ, 1A/1.5A High-Side Dual Power Switches with Flag

General Description

Features

^z90mΩ N-MOSFET Switch

The RT9712 power-distribution switches are designed to

fulfill the applications in heavy capacitive loads and short-

circuit situations. The device incorporates two 90mΩ N-

MOSFET power switches to fit power distribution systems

requiring multiple power switches in a single package.

During switching process, an internal charge pump is

designed to provide the gate drive for the purpose of power-

switch rise times and fall times controlling to minimize

the current surges. The charge pump can operate in supply

voltage as low as 2.7V and needs no external

components.

^zOperating Voltage Range : 2.7V to 5.5V

^zReverse Blocking Current

^zUnder Voltage Lockout

^zDeglitched Fault Report (FLGx)

^zThermal Protection with Foldback

^zOver Current Protection

^zShort Circuit Protection

^zUL Approved−E219878

^zNemko Approved-NO49352

^zRoHS Compliant and Halogen Free

If the output load exceeds the current-limit threshold or a

short-circuit occurs.The RT9712 series pull the overcurrent

(FLGx) logic output low by switching into the constant-

current mode to maintain the output current in a safe level,

A thermal protection circuit turns off the switch to prevent

the device from damage when power dissipation is

increased by continuous heavy overloads and short-circuits

in the switch and finally cause the rise of the junction

temperature. The device automatically recovers when it

has sufficiently cooled down. The RT9712A/B are designed

for the current limit at typically 2A and RT9712C/D are

designed for the current limit at typically 1.5A. Internal

circuitry controls the switch to remain off until valid input

voltage is presented.
