SC-70-6 Smart Load Switch
Final
General Description
The MIC94060 and MIC94061 are smart high-side load
switches housed in the SC-70-6 package. The devices
contain a low on-resistance, 100m
(max) p-channel MOSFET
that is driven by built-in level-shift and slew-rate control
circuitry. The low on-resistance of the devices allows for them
to support over 2A of continuous current. The MIC94061
features an active pull-down circuit that discharges capaci-
tive loads through a 200
switch when the IC is set to the OFF
state.
Pull down circuitry keeps the MIC94060/1 in a default OFF
state until the EN pin is pulled to a high level. The built-in level
shift circuitry allows for a logic signal that may be different
from the supply voltage to switch the high-side P-channel
MOSFET on or off. The 1
μ
s turn-on slew rate control
prevents in-rush current from causing glitches on the supply
rail.
Battery life is saved in portable applications with the IC’s low
quiescent current of 2
μ
A and low shutdown current of <1
μ
A.
Their 1.8V to 5.5V operating voltage range makes the
MIC94060/1 suitable for 1-cell Li Ion, 2- to 3-cell NiMH / NiCad
/ Alkaline, as well as other sub-5V input applications.
Integrating the level-shift and slew-rate control circuitry saves
valuable board space and reduces component placement
cost compared to discrete solutions.
The MIC94060/1 are housed in the Teeny SC-70-6 pack-
age and have a junction temperature range of –40

C to
+150
