AP2146/AP2156
0.5A DUAL CHANNEL CURRENT-LIMITED POWER
SWITCH
Description
• Dual USB port power switches
The AP2146 and AP2156 are integrated high-side power switches
• Over-current and thermal protection
optimized for Universal Serial Bus (USB) and other hot-swap
• 0.8A accurate current limiting
applications. The family of devices complies with USB 2.0 and
• Reverse Current Blocking
• 90mΩ on-resistance
available with both polarities of Enable input. They offer current
and thermal limiting and short circuit protection as well as
• Input voltage range: 2.7V – 5.5V
controlled rise time and under-voltage lockout functionality. A 7ms
• 0.6ms typical rise time
deglitch capability on the open-drain Flag output prevents false
• Very low shutdown current: 1uA (max)
over-current reporting and does not require any external
• Fault report (FLG) with blanking time (7ms typ)
components.
• ESD protection: 6KV HBM, 300V MM
• Active high (AP2146) or active low (AP2156) enable
All devices are available in SOP-8L and MSOP-8L-EP packages.
• Ambient temperature range -40ºC to 85°C
• SOP-8L and MSOP-8L-EP (Exposed Pad): Available in
“Green” Molding Compound (No Br, Sb)
• Lead Free Finish / RoHS Compliant (Note 1)
• UL Recognized, File Number E322375
• IEC60950-1 CB Scheme Certified
Applications
• Consumer electronics – LCD TV & Monitor, Game Machines
• Communications – Set-Top-Box, GPS, Smartphone
• Computing – Laptop, Desktop, Servers, Printers, Docking Station, HUB
