Circuit schematics
The full schematics for the SLLIMM™ 2nd series card for
IPM products is shown below. This
card consists of an interface circuit (BUS and V
CC
connectors), bootstrap capacitors, snubber capacitor,
shortcircuit protection, fault output circuit, temperature monitoring, single-/three-shunt resistors and filters for input
signals. It also includes bypass capacitors for V
CC
and bootstrap capacitors. The capacitors are located very
close to the drive IC to avoid malfunction due to noise.
Dual current sensing options are provided: three dedicated on-board op-amps or embedded MCU op-amps;
selection is performed through three jumpers.
The Hall/Encoder section (powered at 5 V or 3.3 V) completes the circuit.
