9 Power Supply Recommendations
The DRV2511-Q1 device operates from 4.5 V - 26 V and this supply should be able to handle high surge
currents in order to meet the high currrent draws for haptics effects. Additionally the DRV2511-Q1 should have
22-µF and 0.1-µF ceramic capacitors near the PVDD & AVDD pins for additional decoupling from trace routing.
10 Layout
10.1 Layout Guidelines
The EVM layout optimizes for thermal dissipation and EMC performance. The DRV2511-Q1 device has a
thermal pad down, and good thermal conduction and dissipation require adequate copper area. Layout also
affects EMC performance. It is best practice to use the same/similiar layout as shown below in the
DRV2511Q1EVM.
