PCA9452A-EVK Overview
A power management IC (PMIC) is an integrated circuit that combines multiple voltage regulators, sequencing logic, and supervision functions into one device. Within the power-management hierarchy (PMIC -> voltage regulator -> power management subsystem), the PCA9452 consolidates the entire power tree of an i.MX 93x processor platform, reducing board area and bill-of-materials count compared to discrete regulators.
Key features of the kit include full access to all PCA9452A functions: six buck (step-down) DC/DC converters, LDO outputs, I2C-bus control supporting Standard-mode (100 kbit/s), Fast-mode (400 kbit/s) and Fast-mode plus (1 Mbit/s), and configurable power sequencing. The PCA9452 supports I2C address configuration at power-on reset, enabling multi-PMIC systems.
The evaluation board allows engineers to evaluate startup sequencing, regulator output accuracy, load transient response, and I2C register configuration before committing to a custom power-tree design. According to the NXP PCA9452 datasheet and UM11907 evaluation board user manual (Rev. 1.0, February 2024), the kit covers hardware connection, software installation, environment configuration and kit usage.
Typical applications include automotive infotainment, cluster, and ADAS domains built on the i.MX 93x automotive processor family, as well as industrial designs evaluating the PCA9452 power architecture.
A key design consideration: outputs and jumpers on the EVK are configuration points, not final design recommendations; always validate thermal performance and sequencing on your own PCB layout.

Typical Applications
PCA9452A-EVK is suitable for 6 applications: Automotive Infotainment Power Evaluation, ADAS Domain Controller Power Validation, Automotive Cluster and Cockpit Design, PMIC Software and Firmware Development, Industrial Gateway and Edge Computing Power Design, Power Tree Prototyping for New Board Designs.
Automotive Infotainment Power Evaluation
The PCA9452A-EVK lets engineers validate the complete power tree of an i.MX 93x automotive infotainment platform before PCB commit. The PCA9452A provides 11 non-isolated outputs - buck DC/DC converters plus LDOs - that match the rail requirements of i.MX 93x SoC, DDR, and peripheral domains. On the EVK, you can measure startup sequencing order, output accuracy, and load transient response on each rail, then replicate the configuration via the I2C interface (100/400/1000 kbit/s modes). Because the core IC is AEC-Q100 Grade 2 qualified, results transfer directly to production automotive designs with -40 C to +105 C ambient requirements.
Recommended
ADAS Domain Controller Power Validation
ADAS domain controllers built on i.MX 93x processors require precisely sequenced multi-rail power with automotive-grade reliability. The PCA9452A-EVK enables measurement of power-up/down sequencing against the processor's reset requirements, verification of regulator load regulation under transient loads typical of vision/radar processing bursts, and configuration of the I2C register map (address per datasheet Table 17). Engineers can iterate sequencing configurations in software on the EVK instead of respinning PCBs, dramatically shortening the power-tree validation cycle for safety-relevant designs.
Recommended
Automotive Cluster and Cockpit Design
Digital instrument clusters demand low-ripple supplies for display and graphics subsystems. The PCA9452A's combination of step-down converters and LDOs lets designers place low-noise LDO rails on sensitive analog/display circuits while using efficient bucks for high-current digital rails, all controlled through I2C Fast-mode plus (1 Mbit/s). The EVK allows direct comparison of buck versus LDO rail quality on real hardware, including ripple and noise measurements on oscilloscope test points, informing decisions about which PCA9452A output to assign to each cluster rail.
Recommended
PMIC Software and Firmware Development
Embedded teams writing board-support packages and power-management firmware for i.MX 93x automotive systems use the PCA9452A-EVK as a controlled reference platform. The I2C control interface supports Standard-mode (100 kbit/s), Fast-mode (400 kbit/s), and Fast-mode plus (1 Mbit/s) transfers per the NXP datasheet, matching the kernel driver expectations of the production design. Firmware engineers can exercise register writes, verify power-on-reset address configuration (datasheet Table 17), and validate sequencing scripts against real hardware before integration with the processor board.
Recommended
Industrial Gateway and Edge Computing Power Design
Although automotive qualified, the PCA9452A power architecture applies to industrial i.MX 93x-based gateways and edge AI boxes. The EVK allows industrial designers to reuse the validated power tree: 11 non-isolated outputs covering processor core, DDR memory, I/O, and analog rails. Measured efficiency and thermal behavior on the evaluation board feed directly into industrial enclosure thermal calculations. The single-chip PMIC approach reduces BOM count and board area versus discrete regulators, important in compact DIN-rail and fanless edge devices.
Recommended
Power Tree Prototyping for New Board Designs
Hardware teams starting a new i.MX 93x board use the PCA9452A-EVK as a prototyping sandbox. All PCA9452A device features are accessible on the kit: every regulator output, the enable and sequencing logic, and the full I2C register space. Engineers can test non-default output voltages, measure dropout and transient behavior, and confirm that the chosen rail assignments satisfy the i.MX 93x datasheet power requirements. The resulting validated configuration transfers to the schematic as confirmed rail voltages, sequencing order, and capacitor recommendations, reducing first-spin board risk.

Key Differentiators
- Automotive-qualified core PMIC (AEC-Q100 Grade 2) (vs Generic PMIC evaluation kits)
- Purpose-built for i.MX 93x power sequencing (vs MIMX93-EVK)
- Dedicated evaluation kit vs. adjacent PCA9450 kits (vs PCA9450CHNY-EVK)
Design Notes
Evaluation-board measurements do not automatically transfer to production. The EVK uses generous copper pours and short traces; a crowded production PCB can show higher rail ripple and different transient behavior. Reproduce the datasheet layout guidelines (input/output capacitor placement close to the PCA9452 pins) and re-validate startup sequencing and load transients on your own layout before release. Per UM11907, follow the recommended jumper configuration when first powering the board.
When experimenting with output voltage settings over I2C, change regulator set-points one rail at a time and verify the downstream load (especially processor core rails) tolerates the new voltage per the i.MX 93x datasheet operating ranges. The I2C address at power-on reset is defined in Table 17 of the PCA9452 datasheet - confirm the board's address straps match your multi-PMIC bus plan before connecting to a shared bus.
For the eventual production design, treat the EVK as a reference layout: mirror its buck converter switching-loop placement, input capacitor positioning, and ground via stitching. The PCA9452 supports I2C Fast-mode plus (1 Mbit/s); route the I2C bus away from buck switch nodes and use appropriate pull-up values to maintain rise times at 400 kbit/s and above.
