UNISONIC TECHNOLOGIES CO., LTD US94060 Preliminary CMOS IC HIGH SIDE POWER SWITCHES DESCRIPTION The UTC US94060 are high-side load switches incorporating a low on-resistance P-channel MOSFET which provides customers over 2A continuous current. The UTC US94060 is characterized by a fast turn on function. The UTC US94060 keeps in a floating state when an active pull-down signals is on the enable input until a high level signal applies on the EN pin. Built-in level shift circuitry allows low voltage logic signals to switch to higher supply voltages, on the contrary, high level logic signals can control low level voltages. The UTC US94060’s operating voltage varies from 1.8V ~ 5.5V which makes these devices suitable for 1-cell Lithium ion and 2- to 3-cell NiMH/NiCad/Alkaline powered systems as well as all 5V applications. The 2µA low operating current and low shutdown current(less than1µA) make the battery life longer. The UTC US94060 is generally suitable for applications, such as load switch in portable devices: cellular phones, PDAs, MP3 players, digital Cameras, portable instrumentation, battery switch-over circuits and level translators. 5 4 6 1 2 3 SOT-26 FEATURES * Operating voltage range:1.8V ~ 5.5V * Providing 2A continuous operating current * P-channel MOSFET’s RON : 175mΩ typical * Built-in level shift for control logic * Quiescent current is as low as 2µA * Micro-power shutdown less than 1µA ORDERING INFORMATION Ordering Number US94060G-AG6-R Package SOT-26 Packing Tape Reel www.unisonic.com.tw Copyright © 2009 Unisonic Technologies Co., Ltd 1 of 6 QW-R502-382.A US94060 MARKING Preliminary CMOS IC PIN CONFIGURATION VOUT 1 GND 2 EN 3 6 NC 5 GND 4 VIN PIN DESCRIPTION PIN NO. 1 2, 5 3 4 6 PIN NAME VOUT GND EN VIN NC DESCRIPTION Drain of P-channel MOSFET.
