Development kit MLX91208 Melexis development kit MLX91208 Rev 001 06/03/15 1 Description The development kit provides the needed information and components to develop a current sensor based on MLX91208. The main goal is to show the functionalities and the features of the part in a simple and effective way. The kit includes: 3 samples MLX91208-CAH 3 samples MLX91208-CAL 1 separate PCB EC01 1 separate PCB EC02 1 separate PCB EC03 3 shields U 12 2 shields R 12 The kit does not include a bus bar. Datasheet and Application Note can be found on www.melexis.com Rev 001 Page 1 of 12 LCO March 6, 2015 Development kit MLX91208 2 PCBs layout The kit includes different PCB layout to cover different current ranges. The EC-01 has a single trace whereas the EC-02 and EC-03 PCBs offer coil-like design with multiple windings, which increases the magnetic flux density and therefore the sensor sensitivity. PCB EC-01(single trace) for U-shield and C-shield The top layer (105 um) is a conductor. The bottom layer is an expanded ground layer Layer: TOP- layer Bottom- layer (1) Current: We recommend : MAX 30A RMS for PCB application Dimension l/b/h : 36.8mm x 30.5mm x 1.6mm (1): The maximum current is limited by the PCB. For higher currents (> 30A), one can use an external conductor (i.e. a bus bar). PCB EC-02 (three windings) The top three layers have one conductor trace (3 windings total). The bottom layer is an expanded ground. Top- layer Second- layer Layer Third - layer Bottom- layer (1) Current: We recommend : MAX 30A RMS for PCB application Dimension l/b/h : 36.8mm x 30.5mm x 2mm (1): The maximum current is limited by the PCB. For higher currents (> 30A), one can use an external conductor (i.e. a bus bar). Rev 001 Page 2 of 12 LCO March 6, 2015
