 PI2161 Product Description

The Cool-Switch

Disconnect

Switch

solution

for

medium

voltage

applications with a high-speed electronic circuit breaker

and a very low on-state resistance MOSFET.

It is

designed to protect an input power bus from output load

fault conditions.

The PI2161 Cool-Switch solution is

offered in an extremely small, thermally enhanced 7mm x

8mm LGA package. The PI2161 enables an extremely low

power loss solution with fast dynamic response to an

over current fault or

high conditions. The PI2161

senses a small portion of the total MOSFET current and

has a low voltage threshold allowing the use of low

power sense resistors.

Figure 1,

shows a photo of the PI2161-EVAL1 evaluation

board with one load disconnect switch PI2161 SiP. The

board is built with options and features that enable the

user to fully explore the capabilities of the PI2161 Load

Disconnect Switch.
