Introduction
The DRV10963 EVM is an evaluation platform for the DRV10963 5-V three phase sensor-less BLDC
motor driver. The EVM is a combination of a motherboard and daughterboard. The motherboard includes
a TLC555 timer configured to supply a PWM to the DRV10963 and a potentiometer to adjust the speed of
the motor by varying the duty cycle of the PWM and has USB2ANY connector to communicate with
DRV10963 GUI. The daughterboard contains a socket allowing the device to be programmed using the
DRV10963 GUI via I
2
C communication and it is mounted on top motherboard, as shown in
. The
EVM set-up, together with DRV10963 GUI also provides means to program OTP (one time
programmable) of DRV10963 blank version (un-programmed OTP) device for any custom motor solution.
The DRV10963 GUI is easy to use, requires only four simple steps to tune the motor for any end
application and program the device OTP. The DRV10963 EVM comes with blank version device with un-
programmed OTP bits. The DRV10963 device has configurable shadow registers corresponding to each
OTP bit. Shadow registers provide ease-of-tuning to the user, as their values can be changed indefinitely
during the course of tuning to arrive at the best optimized values. The DRV10963 also has an I
2
C
interface, this allows the user to program specific motor parameters in shadow registers, before deciding
on final values to program OTP. Note that configurable shadow registers are volatile and lose their values
in power off condition.
This document describes the kit details and explains the functions and locations of test points, jumpers,
and connectors present on the kit. This document is also a quick start guide for using the GUI to tune a
motor for an end application. For detailed information about the DRV10963, refer to the DRV10963 data
