Monolithic Power Systems Inc. TBMA330-Q-LT-00A

Overview

TBMA330-Q-LT-00A from Monolithic Power Systems is a long-format (LT) evaluation board designed specifically for the MA330 MagAlpha magnetic position sensor. It supports both side-shaft and end-of-shaft mounting configurations, provides SPI interface access (CS, SCLK, MISO, MOSI), and delivers 3.3V power and test functionality via dual 8-pin headers. It enables rapid functional validation of MA330-based angle sensing in motor control and encoder applications.

For engineers reviewing the TBMA330-Q-LT-00A datasheet, TBMA330-Q-LT-00A pinout, TBMA330-Q-LT-00A application, or TBMA330-Q-LT-00A equivalent, this board serves as a ready-to-use platform to evaluate MA330 sensor performance-including incremental A/B/Z outputs, PWM, and optional commutation signals-without custom PCB design.

Technical Context

The TBMA330-Q-LT-00A implements Board Type 1 architecture per the TBMA User Guide Rev. 1.2, matching the schematic and pin register layout defined for MA300/MA330-series sensors. It routes all core SPI signals (CS, SCLK, MISO, MOSI), VDD (3.3V), GND, VFLASH (3.9V flash supply), and TEST pin to CN1, while CN2 exposes U/V/W motor commutation outputs and A/B/Z incremental encoder outputs-consistent with MA330's functional pin mapping.

This board integrates two 1µF X6S 0402 decoupling capacitors (C1, C4), one optional 100nF X7R 0402 capacitor (C3), and leaves CN1/CN2 connectors unpopulated by default-requiring user-supplied 2.54mm 8-position receptacles (e.g., Wurth 690367280876). Its mechanical form factor supports direct integration into servo or BLDC test fixtures using edge-mounting.

FAQ

What sensor does the TBMA330-Q-LT-00A support?

The TBMA330-Q-LT-00A is designed exclusively for the MA330 MagAlpha magnetic position sensor. It maps all MA330-specific pins-including U/V/W motor outputs and A/B/Z incremental encoder signals-to its dual 8-pin headers, and follows the Type 1 LT schematic and layout defined in the official TBMA User Guide Rev. 1.2.

Are connectors included with the TBMA330-Q-LT-00A board?

No, CN1 and CN2 connectors are not populated on the TBMA330-Q-LT-00A board. Users must supply their own 2.54mm pitch, 8-position surface-mount receptacle connectors-such as Wurth 690367280876 or TE Connectivity 7-2178711-8-as specified in the Bill of Materials for Type 1 boards.

Does the TBMA330-Q-LT-00A support both side-shaft and end-of-shaft configurations?

Yes, the TBMA330-Q-LT-00A's long (LT) mechanical format places the MA330 sensor at the board edge, enabling direct mechanical coupling in either side-shaft or end-of-shaft arrangements without adapter hardware-verified in the TBMA User Guide Rev. 1.2 mechanical drawings and application notes.

Which evaluation kits is the TBMA330-Q-LT-00A compatible with?

The TBMA330-Q-LT-00A is explicitly compatible with the EVKT-MagAlpha-MagDiff and EVKT-MACOM evaluation kits, as confirmed in the "Compatibility" section of the TBMA User Guide Rev. 1.2. This ensures seamless signal routing, power sequencing, and debug interface alignment across platforms.

What passive components are assembled on the TBMA330-Q-LT-00A board?

The board ships with two populated 1µF X6S 0402 ceramic capacitors (C1, C4) for VDD decoupling, and one optional 100nF X7R 0402 capacitor (C3) for additional filtering-per Table 2 (Type 1 BOM) in the TBMA User Guide Rev. 1.2. No resistors or other passives are mounted.
