US301

UNISONIC TECHNOLOGIES CO., LTD US301 Preliminary 0.2A SINGLE CHANNEL CURRENT-LIMITED LOAD SWITCH  DESCRIPTION The UTC US301 is single channel current-limited integrated high-side power switches, optimized for hot-swap applications. The US301 provides a complete protection solution for application subject to heavy capacitive loads and the prospect of short circuit. The devices have fast short-circuit response time for improving overall system robustness, and offer reverse-current blocking, over-current and over-temperature protection, as well as under-voltage lockout functionality. It also has controlled built-in soft-start time, typically 0.7 ms.  FEATURES * Input voltage range: 2.7V~5.2V * Short-circuit protection and fast response time * Accurate current limiting: 0.4A * On-resistance:250 mΩ * Reverse-current blocking * Soft-start with 0.7ms typical turn-on time * Over-current and over-voltage protection * Thermal protection * Ambient temperature range: -40°C~+85°C  ORDERING INFORMATION Ordering Number US301G-AE2-R Package SOT-23-3 CMOS IC Packing Tape Reel  MARKING 301G www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd 1 of 4 QW-R103-099.a US301  PIN CONFIGURATION Preliminary CMOS IC  PIN DESCRIPTION PIN NO. 1 2 3 PIN NAME GND OUT IN GND Switch output pin Voltage input pin DESCRIPTION UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 4 QW-R103-099.a US301 Preliminary CMOS IC  ABSOLUTE MAXIMUM RATING PARAMETER SYMBOL ...
