Features

are programmed in the MCU provided with the DB62: 1. User Controlled PWM frequency using external potentiometer (VFREQ in EVAL 49 board). The PWM frequency can be varied from 4 KHz to 118 KHz. 2. User Controlled PWM duty cycle using external potentiometer (VDUC in EVAL49 board). The voltage set by the potentiometer will act as a ‘Speed Reference’. The duty cycle can be varied from 0 % to 98 %. The Forward/Reverse button is provided to control the direction of the motor. Depending upon the dire.

"1&9 INTRODUCTION The DB62 is designed to demonstrate the capabilities of the SA305 as a 3 phase brushless DC motor driver IC. The PWM inputs to the SA305 are controlled by an on-board microcontroller. The EVAL49 board is pre-wired for all required and recommended external components. Please refer to applications note 32 in the Apex catalog for guidance in filter component selection. The 1µF ceramic capacitors supplied with the kit are for high frequency bypassing of the VS and VDD supplies (C1, C11, C4 and C7 on the EVAL49 schematic). Two additional 100uF bypass capacitors are provided with the kit for the VS supplies (C2 and C12 on the EVAL49 schematic).
