Richtek USA Inc. RT9711BGS
- Part Number:
- RT9711BGS
- Manufacturer:
- Richtek USA Inc.
- Ventron No:
- 3264617-RT9711BGS
- Description:
- IC PWR SWITCH USB 1.5A 8SOP
- Datasheet:
- RT9711BGS
Description
The RT9711A/B/C/D are cost-effective, low voltage, single N-MOSFET high-side power switches, optimized for self-powered and bus-powered Universal Serial Bus (USB) applications. The RT9711 series are equipped with a charge pump circuitry to drive the internal MOSFET switch. The switch's low Ros(ON), 80mΩ, meets USB voltage drop requirements. A flag output is available to indicate fault conditions to the local USB controller.
Features
Compliant to USB Specifications
Built-In N-MOSFET
Typical Ros(ON): 80mΩ (SOT-23-5 & TSOT-23-5) and 90mΩ (SOP-8 & MSOP-8)
Output Can Be Forced Higher Than Input (Off-State)
Low Supply Current:
25μA Typical at Switch On State
1μA Typical at Switch Off State
Guaranteed 1.5A for RT9711A/B and 0.6A for RT9711C/D Continuous Load Current
Wide Input Voltage Ranges: 2.5V to 5.5V
Open-Drain Fault Flag Output
Hot Plug-In Application (Soft-Start)
1.7V Typical Under-Voltage Lockout (UVLO)
Current Limiting Protection
Thermal Shutdown Protection
Reverse Current Flow Blocking (no body diode)
Smallest SOT-23-5 and TSOT-23-5 Packages Minimizes Board Space
UL Approved-E219878
TUV IEC60950-1 : 2005 Certified
RoHS Compliant and 100% Lead (Pb) -Free
Applications
USB Bus/Self Powered Hubs
USB Peripherals
ACPI Power Distribution
PC Card Hot Swap
Notebook, Motherboard PCs
Battery-Powered Equipment
Hot-Plug Power Supplies
Battery-Charger Circuits
