Texas Instruments TPS659037EVM-090

Overview

TPS659037EVM-090 from Texas Instruments is an evaluation module designed to validate and configure the TPS659037 power-management IC (PMIC) for industrial and consumer processor systems. It enables full register access via USB-I2C bridge, real-time monitoring of all 7 SMPS outputs and 7 LDOs, GPIO testing, and programmable power sequencing using a Windows-based GUI.

For engineers reviewing the TPS659037EVM-090 datasheet, TPS659037EVM-090 pinout, TPS659037EVM-090 application, or TPS659037EVM-090 equivalent, this EVM provides hands-on validation of PMIC rail configuration, dynamic voltage scaling, fault response, and system-level power sequencing - critical for embedded processor platforms requiring multi-rail coordination and low-power state management.

Technical Context

The TPS659037EVM-090 integrates an MSP430F5529 microcontroller that acts as a USB-to-I2C bridge, enabling bidirectional communication with the TPS659037 PMIC over I2C1 and I2C2 buses. It supports full register read/write, static pin control (RESET_IN, PWRDOWN, NSLEEP, ENABLE1), and scripted power-up/down sequences via LabVIEW-based GUI.

Hardware features include four-wire VSYS input sensing (3.135 V–5.25 V), jumper-configurable VIO selection (1.8 V or 3.3 V), 44-pin LDO output test points (J46), 12-pin GPIO access (J27), and dedicated monitor points for all SMPS outputs (SMPS12/3, SMPS3, SMPS45, SMPS6–9). Onboard LEDs indicate POWERGOOD, RESET_OUT, LDORTC, and MSP430 status.

FAQ

What is the primary function of the TPS659037EVM-090?

The TPS659037EVM-090 is an evaluation module for the TPS659037 PMIC, enabling engineers to configure, monitor, and validate its 7 buck converters and 7 LDOs in real time. It uses an onboard MSP430F5529 to translate USB commands into I2C transactions, allowing full register access and GPIO control without requiring a host processor. This makes the TPS659037EVM-090 essential for early-stage power architecture verification and firmware co-development.

Does the TPS659037EVM-090 support power sequencing scripts?

Yes, the TPS659037EVM-090 supports automated power sequencing via its LabVIEW-based GUI script editor. Users can record or manually write scripts using tlv_write_reg_i2c1(REGISTER_NAME, VALUE) and wait(TIME_IN_MS) commands to sequence SMPS enablement (e.g., SMPS12 → SMPS3), set voltages, and insert delays - replicating boot-up or low-power transition behavior of the target system without manual intervention.

How is the TPS659037EVM-090 powered?

The TPS659037EVM-090 receives main power via the VSYS domain (3.135 V–5.25 V DC) applied to J20, which powers the TPS659037 PMIC. The MSP430F5529 microcontroller and fixed 3.3 V/1.8 V LDOs are powered separately through the USB connection. Four-wire sensing on J20 is recommended for accurate input voltage measurement and stability during load transients.

Can the TPS659037EVM-090 be used to test GPIO functionality of the TPS659037?

Yes, the TPS659037EVM-090 provides direct access to all 8 GPIOs (GPIO_0 through GPIO_7) via J27, a 12-position dual-row header. These signals are routed to the MSP430F5529 and controllable through the DUT_Control tab in the GUI. Engineers can assert logic high/low states, monitor responses, and verify GPIO-driven functions such as reset propagation, interrupt signaling, or external peripheral enable control - all without modifying hardware.

Is the TPS659037EVM-090 FCC-certified for emissions compliance?

No - the TPS659037EVM-090 is an evaluation module intended solely for R&D use and is not FCC-certified as a finished product. Per TI's Standard Terms and Conditions for Evaluation Modules, it must be operated in a shielded lab environment or under experimental authorization if radiated emissions testing is required. It complies with Class A digital device limits per FCC Part 15 when tested in commercial settings but is not authorized for resale or integration into end products without full system-level certification.
