NXP Semiconductors KITVR5500AEEVM

Overview

KITVR5500AEEVM from NXP Semiconductors is an evaluation board designed for the VR5500 and FS5502 automotive high-voltage PMICs, supporting development of multi-rail power systems with up to 10 A VPRE output, 3.6 A BUCK3, and OTP programming capability. It enables register-level I²C access, multiphase BUCK1/BUCK2 configuration (VR5500), and voltage monitoring for truck 24 V systems sustaining up to 60 V VBAT.

For engineers reviewing the KITVR5500AEEVM datasheet, KITVR5500AEEVM pinout, KITVR5500AEEVM application, or KITVR5500AEEVM equivalent, this page delivers verified hardware interface details, FlexGUI software integration guidance, OTP fuse sequencing support, VPRE compensation network values, and jumper-configurable regulator monitoring - all specific to the shipped KITVR5500AEEVM Rev. 1 board.

Technical Context

The KITVR5500AEEVM integrates a pre-soldered VR5500/FS5502 PMIC and KL25Z MCU to enable real-time register read/write via USB-connected FlexGUI. It supports both Emulation mode (volatile configuration) and OTP mode (three-fuse persistent configuration), with on-board 8 V DBG voltage generation from USB for secure programming without external supplies.

Hardware flexibility includes jumper-selectable VDDI2C (1.8 V or 3.3 V), VMON1 routing (VPRE or fixed 0.8 V), VDDIO sourcing (LDO1/LDO2/BUCK3/VDDI2C), and BUCK1/BUCK2 multiphase enablement via R7/R8 zero-ohm resistors - all validated for ASIL-QM automotive applications in radio, V2X, and infotainment systems.

FAQ

What is the primary function of the KITVR5500AEEVM evaluation board?

The KITVR5500AEEVM evaluation board is a hardware development tool for the VR5500 and FS5502 automotive high-voltage PMICs. It enables full-feature evaluation including register access via FlexGUI, OTP configuration burning (up to three times), VPRE compensation tuning, multiphase BUCK1/BUCK2 setup (VR5500 only), and real-time monitoring of all regulator outputs and status signals. The KITVR5500AEEVM ships with a pre-soldered superset device and supports both Emulation and OTP operational modes.

Which devices does the KITVR5500AEEVM support, and are they pin-compatible?

The KITVR5500AEEVM supports both the VR5500 and FS5502 PMICs, which are pin-to-pin and software compatible with each other and with NXP's FS84 (ASIL-B) and FS85 (ASIL-D) devices. This allows a single KITVR5500AEEVM board to validate multiple derivatives across the family without hardware changes. The board is populated with a superset part and uses jumpers and resistors to configure functionality per target device, such as enabling BUCK2 or BOOST only for VR5500.

How does OTP programming work on the KITVR5500AEEVM, and what safeguards exist?

OTP programming on the KITVR5500AEEVM uses an on-board 8 V DBG voltage generated from USB - eliminating need for external programming supplies. The board includes SW3 switch and blue LED (D11) to indicate >8.0 V on DBG during fuse operations. Three OTP sectors (S1, S1bis, S1ter) are available; FlexGUI manages sector selection automatically. Once fused, prior sectors cannot be reverted, but Emulation mode remains fully usable for iterative testing. The KITVR5500AEEVM implements hardware-level Debug mode entry sequence per UM11304 Section 4.2.2.

What power supply requirements must be met to operate the KITVR5500AEEVM?

The KITVR5500AEEVM requires a DC input of 8.0 V to 60 V at VBAT, with initial current limiting set to 1.0 A. Power can be supplied via either the Phoenix connector (J1) or barrel jack (J9), selected using SW1. USB provides 5 V for KL25Z MCU, FlexGUI communication, and on-board LDOs (VDDI2C, VDDIO). For OTP programming, the DBG pin must reach ≥8.0 V - achieved internally from USB via dedicated DC-DC converter, not from external VBAT.

Can the KITVR5500AEEVM be used for ASIL-B or ASIL-D system development?

Yes - the KITVR5500AEEVM evaluates VR5500 and FS5502 devices that are pin- and software-compatible with FS84 (certified ASIL-B) and FS85 (certified ASIL-D). While the evaluation board itself is not safety-certified, its hardware design - including six-layer PCB stack-up, thermal-aware layout, and configurable monitoring - supports development of safety-critical power architectures. Engineers must implement final system-level safety mechanisms (e.g., redundancy, diagnostics, layout controls) per ISO 26262, as stated in UM11304 Section 1.
