4.2 Overview
A set of schematics for the SMOS EVM motor board appears in
Figure 4-1 up to Figure 4-5. An overview of the whole board is
presented in Figure 4-1 (or Figure 4-1a ) . The 3-phase H-bridge,
including gate driver, is depicted in Figure 4-2. Current feedbacks are
presented in Figure 4-3. Back-EMF signals are shown in Figure 4-4.
The brake control is illustrated in Figure 4-5. Brushless dc motor
connections are shown in Figure 4-6.
Unless otherwise specified, resistor values are in ohms, resistors are
specified as 1/8 watt ±5%, and interrupted lines coded with the same
letters are electrically connected.
