AP2186/ AP2196

1.5A DUAL CHANNEL CURRENT-LIMITED POWER SWITCH

Description

The AP2186 and AP2196 are integrated high-side power switches optimized for Universal Serial Bus (USB) and other hot-swap applications. The family of devices complies with USB 2.0 and available with both polarities of Enable input. They offer current and thermal limiting and short circuit protection as well as controlled rise time and under-voltage lockout functionality. A 7ms deglitch capability on the open-drain Flag output prevents false over-current reporting and does not require any external components.

All devices are available in SO-8 and MSOP-8EP packages

Features

 Dual USB Port Power Switches  Over-Current and Thermal Protection  2.1A Accurate Current Limiting  Reverse Current Blocking  90m On-Resistance  Input Voltage Range: 2.7V - 5.5V  0.6ms Typical Rise Time  Very Low Shutdown Current: 1µA (max)  Fault Report (FLG) with Blanking Time (7ms typ)  ESD Protection: 6KV HBM, 300V MM  Active Low (AP2186) or Active High (AP2196) Enable  Ambient Temperature Range -40ºC to +85°C  SO-8 and MSOP-8EP (Exposed Pad): Available in “Green”

 Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)  Halogen and Antimony Free. “Green” Device (Note 3)

 UL Recognized, File Number E322375  IEC60950-1 CB Scheme Certified

Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant.

2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and Lead-free.

3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and <1000ppm antimony compounds.
