STMicroelectronics EVAL-D-L99DZ100G

Overview

EVAL-D-L99DZ100G from STMicroelectronics is a daughterboard evaluation platform for the L99DZ100G automotive door zone IC, featuring six configurable high-side drivers (including 7.5 A, 3 A, 0.5 A, and 0.15–0.5 A variants), dual CAN/LIN transceivers, electro-chromic control, and two 5 V regulators - designed specifically for front-door module validation in vehicle body electronics.

For engineers reviewing the EVAL-D-L99DZ100G datasheet, EVAL-D-L99DZ100G pinout, EVAL-D-L99DZ100G application, or EVAL-D-L99DZ100G equivalent, this board enables rapid functional verification of L99DZ100G's multi-load driving capability, thermal-safe fail-safe architecture, programmable soft-start, and real-time diagnostic telemetry via STM8-based GUI-controlled interface.

Technical Context

The EVAL-D-L99DZ100G implements the L99DZ100G's full analog/digital peripheral set on a dedicated daughterboard, interfacing with a separate STM8-based motherboard that handles LIN/CAN protocol stack, watchdog supervision, and GUI communication. It supports isolated fail-safe logic with dual 1 mΩ low-side pull-downs for external HS MOSFET gate control.

It integrates internal 10-bit PWM timers per standalone high-side driver, buffered supply rails for external contact actuation (OUT15 & OUT_HS), and A/D conversion of supply voltages and die temperature - all configured and monitored through the demonstration GUI over USB.

FAQ

What is the difference between EVAL-D-L99DZ100G and EVAL-L99DZ100G?

EVAL-D-L99DZ100G is the daughterboard only - it hosts the L99DZ100G IC and associated driver circuitry but requires the separate EVAL-L99DZ100G motherboard (with STM8 MCU, CAN/LIN transceivers, and GUI interface) to operate. The full evaluation kit comprises both boards.

Does EVAL-D-L99DZ100G support electro-chromic glass control?

Yes - it includes a dedicated high-side driver (0.25 A / 0.5 A, R_ON = 2 Ω) optimized for EC glass MOSFET gate drive, along with embedded VS duty cycle adjustment logic for LED driver outputs, as specified in the L99DZ100G datasheet and confirmed in ST's application schematics.

Can EVAL-D-L99DZ100G be used without the motherboard?

No - the daughterboard lacks microcontroller, communication transceivers, and GUI interface logic. It relies entirely on the motherboard for configuration, diagnostics, and protocol handling. ST's documentation explicitly defines it as a "daughter board" requiring the motherboard for operation.

Is the CAN transceiver on EVAL-D-L99DZ100G ISO 11898-6 compliant?

Yes - the L99DZ100G IC integrated on the board includes an advanced high-speed CAN transceiver compliant with ISO 11898-2:2003, -5:2007, and -6:2013 (selective wake-up and bus failure diagnosis), as stated in the official ST data brief and confirmed in Table 1 and Section 1.
