MIC2095 Overview

1-CHANNEL POWER SUPPLY SUPPORT CKT, PDSO6

MIC2095/MIC2097/MIC2098/MIC2099
Current-Limiting Power Distribution Switches
General Description
The MIC2095/97/98/99 family of switches are self-
contained, current-limiting, high-side power switches, ideal
for power-control applications. These switches are useful
for general purpose power distribution applications such as
digital televisions (DTV), printers, set-top boxes (STB),
PCs, PDAs, and other peripheral devices.
The current limiting switches feature either a fixed
0.5A/0.9A or resistor programmable output current limit.
The family also has fault blanking to eliminate false noise-
induced, over current conditions. After an over-current
condition, these devices automatically restart if the enable
pin remains active. The MIC2097 switch offers a unique
new patented Kickstart feature, which allows momentary
high-current surges up to the secondary current limit
(I
LIMIT_2nd
). This is useful for charging loads with high inrush
currents, such as capacitors.
The MIC2095/97/98/99 family of switches provides under-
voltage, over-temperature shutdown, and output fault
status reporting. The family also provides either an active
low or active high, logic level enable pin.
The MIC2095/97/98/99 family is offered in a space saving
1.6mm x 1.6mm Thin MLF
®
(TMLF) package.

A question about connection, who has done it, come in and take a look? (WinCE)
It's a very simple situation. I used PB4.2 to compile an OS, and then made a Dos system on VMWare6.0, and then made a bootdisk! Then I wanted to download NK.BIN directly to VMWare through PB. My local...
