Product specifications

DB73HR - DemoBoard for Slug Down version of SA306AHR

The DB73HR is designed to demonstrate the capabilities of the SA306 3-phase brushless DC (BLDC) motor driver IC.
This fully assembled demonstration allows the user to directly control the speed and direction of the motor. An onboard controller decodes HALL Effect sensor inputs for commutation in either direction and provides four quadrant PWM signals to control the power outputs of the SA306. LEDs provide visual feedback for motor control status and fault indications. Provisions on the DB73HR allow the user to bypass the onboard control circuit and directly interface with the SA306 brushless motor driver.
The DB73HR demonstrates proper layout techniques for the SA306 high current switching amplifier. The economical construction uses only a two-sided PCB and allows the SA306 to dissipate up to 5W.

THERMAL CONSIDERATIONS
The SA306 is offered in a surface mount package which can deliver peak power of over 1kW. This presents an obvious and significant thermal challenge. The DB73HR offers a compact design which can deliver 17A peak current. The DB73HR assembly can dissipate approximately 5W in still air at 25ºC ambient temperature. To use the DB73HR in higher power applications, use of a fan is recommended. Although the SA306 is rated for operation from -25 to +85ºC, the other components on the DB73HR are limited to 0 to 70ºC ambien temperature.

CIRCUIT OPERATION
The DB73HR control circuit receives power via two terminal block connections. The Vs connection supplies power to drive the motor and must be above the under-voltage lockout threshold of the SA306, approximately 8.3V. The control circuit requires 12V for proper operation. A regulator on the DB73HR provides the 5V logic supply for the SA306.
There are no special considerations for sequencing the two supplies.
