Component building blocks

Functional blocks for selection; device connections and component values depend on your design.

FUNCTION / 01

Brushless motor control

Use the brushless DC controller and its speed-feedback adapter to build a motor control loop. These control devices require an appropriate external power stage.

FUNCTION / 02

MOSFET gate drive

Drive external MOSFET gates from controller logic. Check gate charge, peak drive current, voltage and switching timing.

FUNCTION / 03

Rotor-position conversion

Convert resolver signals into digital position data for a control loop.

FUNCTION / 04

Current monitoring

Amplify the voltage across a current-sense resistor. Check input common-mode range, gain and error budget.
