Detailed Description for MAX1946ETA+T
Product Overview
The MAX1946ETA+T from Analog Devices Inc./Maxim Integrated is a power management integrated circuit intended for USB and peripheral applications. It is packaged in an 8-TDFN (3x3) surface-mount package with an exposed pad, supporting compact board layouts. The device operates from a 2.7 V to 5.5 V supply and has a specified supply current of 40 µA. Its rated operating temperature range is -40°C to 85°C, making it suitable for designs operating within those environmental limits.
Key Features
- Provides a single USB switch function with feedback for peripheral power management.
- Operates from a 2.7 V to 5.5 V supply.
- Specified supply current is 40 µA.
- Rated for operation from -40°C to 85°C.
- Surface-mount package with an 8-WDFN exposed pad.
- Uses an 8-TDFN (3x3) package.
Applications
- USB peripheral power control in embedded systems and accessory interfaces.
- Single-switch USB port management in compact board assemblies.
- Power switching for USB-connected peripherals in space-constrained designs.
Design & Procurement Notes
Designers selecting the MAX1946ETA+T should confirm that the system supply voltage remains within 2.7 V to 5.5 V and that the operating environment does not exceed the specified -40°C to 85°C range. The 40 µA supply current should be included in power budget calculations for USB peripheral subsystems. Because the device uses an 8-TDFN (3x3) surface-mount package with an 8-WDFN exposed pad, PCB footprint, pad geometry, solder mask clearance, and mounting considerations should be reviewed during layout. The exact manufacturer part number should be retained in the bill of materials to ensure the specified package and device variant are used.
