Product details

Overview

MA330051-2 from Microchip Technology is a motor control Plug-In Module (PIM) built around the dsPIC33CK64MC105 16-bit Digital Signal Controller, featuring three integrated operational amplifiers for current sensing, high-resolution PWM generation, and shared ADC resources. It is designed for single-motor Field-Oriented Control (FOC) and single-stage boost Power Factor Correction (PFC) demonstration on compatible development boards.

For engineers reviewing the MA330051-2 datasheet, MA330051-2 pinout, MA330051-2 application, or MA330051-2 equivalent, this PIM enables rapid validation of internal op amp–based motor control topologies-including shunt-based phase current acquisition, differential amplifier gain configuration, and analog filter design-using dsPICDEM MCLV-2, MCHV-2, or MCHV-3 platforms.

Technical Context

The MA330051-2 implements hardware-level signal conditioning for motor phase currents via three dedicated internal op amps (OA1–OA3), each with configurable low-pass filtering and differential amplification using external passive networks (e.g., R = 499 Ω, C = 470 pF, C_boost = 1000 pF). Each op amp supports common-mode rejection up to ~680 kHz and differential-mode bandwidth ~129 kHz per channel.

It maps the 48-pin dsPIC33CK64MC105 TQFP device to a standardized 100-pin PIM interface, preserving all critical motor control peripherals: six PWM pairs (PWM1H/L through PWM4H/L), multiple ADC inputs (AN0–AN15), oscillator pins (OSCI/OSCO), and debug interfaces (PGD/PGC). Analog and digital power domains (AVDD/AVSS, VDD/VSS) are physically separated but internally tied via configurable 0 Ω resistors (e.g., R22).

FAQ

What is the primary function of the MA330051-2?

The MA330051-2 is a Plug-In Module that hosts the dsPIC33CK64MC105 DSC and exposes its internal operational amplifiers for motor phase current sensing and conditioning. It enables hardware-validated FOC and PFC development without external op amp circuitry, directly supporting shunt-resistor-based current feedback loops on compatible Microchip development boards.

Which development boards are compatible with the MA330051-2?

The MA330051-2 is verified for use with dsPICDEM MCLV-2 (DM330021-2), dsPICDEM MCHV-2 (DM330023-2), and dsPICDEM MCHV-3 (DM330023-3) development boards across all hardware revisions. It is explicitly not compatible with earlier MCLV, MCHV, or Low-Voltage Motor Control Bundle platforms.

How are the internal op amps configured on the MA330051-2?

The MA330051-2 uses external passive components (e.g., 499 Ω resistors and 470 pF/1000 pF capacitors) to configure each of the three internal op amps as differential amplifiers with gain ≈15.03 and dual-pole low-pass filtering. Pin mappings (e.g., PIM:66 for OA1IN−/OA3IN+/OA2IN−) allow flexible routing to shunt resistor nodes IA, IB, and IBUS.

Does the MA330051-2 require an external op amp configuration board?

Yes - operation requires insertion of an internal op amp configuration matrix board onto J14 (MCLV-2) or J4 (MCHV-2/MCHV-3). This board provides the passive network (resistors/capacitors) needed to set gain, bandwidth, and bias for OA1–OA3. The MA330051-2 itself contains no active op amp configuration logic.

What safety precautions apply when using the MA330051-2 with high-voltage boards?

Non-isolated oscilloscope probes must not be connected to test points on the MA330051-2 while operating with dsPICDEM MCHV-2 or MCHV-3 boards. Doing so risks damaging both the PIM and development board due to ground loop voltage differences between the isolated power stage and controller domain.
