ACSEVB-EX12 Evaluation Board
ACS71240 - Cost-Effective Shunt Alternative Hall-based Current Sensor
BaBare evaluation boards offer a method for evaluating
Allegro current sensors in a lab environment. This document
describes the use of the EX Package Bare Evaluation Board.
This evaluation board (ACSEVB-EX12, TED-0004113) is
intended for use with any EX packaged Allegro current sensor
(EXB 12-contact QFN with wettable flank).
Enhanced thermal performance
□ 6-layer PCB with 2 oz copper weight on all layers
Nonconductive-filled via-in-pad
High-performance FR4 material with 180°C glass
transition temperature
Flexible layout for user installed connection points
Standard Keystone test points
SMA/SMB connector
2-pin headers
Integrated current loop resistance can be measured directly
on the evaluation board after test point installation; voltage
drop can be measured for approximating power loss in the
package.
NOTE: It is the responsibility of the user to assemble
the board with the desired current sensor and supporting
circuitry. This board does not come populated with an
Allegro current sensor or other components.
Recommended supporting circuitry for all compatible
current sensors is listed in the Supporting Circuitry
section.
