Product details
Overview
L99DZ100GPTR from STMicroelectronics is an AEC-Q100 qualified automotive door zone IC integrating dual high-speed CAN (ISO 11898-2/5/6 compliant with selective wake-up), LIN 2.2a transceiver, 15 configurable power outputs (including 4 half-bridges, 11 high-side drivers), two 5 V regulators, programmable PWM timers, and electro-chromic glass control - deployed in vehicle door modules for window lift, mirror fold, lock actuation, and EC mirror dimming.
For engineers reviewing the L99DZ100GPTR datasheet, L99DZ100GPTR pinout, L99DZ100GPTR application, or L99DZ100GPTR equivalent, this page delivers verified technical context on integrated HS-CAN selective wake-up capability, output RON values (100–2000 mΩ), thermal supervision clusters, fail-safe low-side gate pull-down, and SPI-configurable soft-start for inrush-limited loads.
Technical Context
This device implements a multi-output power management and communication SoC architecture for automotive door ECUs. It integrates two independent CAN physical layers (one supporting ISO 11898-6 partial networking), a LIN transceiver, and a 32-bit SPI interface for register-level configuration of all drivers, watchdogs, and monitoring functions.
The power stage comprises four dedicated half-bridge outputs (7.5 A / 3 A rated) plus eleven programmable high-side drivers with selectable current ratings (0.15–1.5 A) and per-channel 10-bit PWM timers. All outputs feature embedded open-load detection, overcurrent shutdown, thermal warning, and current monitor feedback.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp Range | −40 °C to +150 °C junction - supports under-hood and door module placement without external heatsinking. |
| CAN Compliance | ISO 11898-2:2003 / -5:2007 / -6:2013 - enables selective wake-up from standby via bus activity without full network arbitration. |
| LIN Compliance | SAE J2602 / LIN 2.2a - provides diagnostics, sleep/wake coordination, and slave node control in body domain networks. |
| Output RON (Max) | 100 mΩ (HB1), 150 mΩ (HB2), 300 mΩ (HB3/4), 500–2000 mΩ (HS drivers) - defines conduction loss and thermal derating at rated load currents. |
| Supply Regulators | V1: 5 V / 150 mA; V2: 5 V / 100 mA - powers MCU core and peripherals while maintaining independent fault isolation. |
| Protection Features | Open-load, overcurrent, thermal warning/shutdown, drain-source monitoring, cross-current protection - eliminates need for external sense resistors or discrete supervisors. |
| PWM Resolution | 10-bit per high-side driver - enables precise LED dimming, heater ramping, and motor microstepping control. |
Pinout & Package
L99DZ100GPTR is housed in a thermally enhanced LQFP-64 EPAD package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad for PCB heat dissipation and mechanical stability in automotive vibration environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Main supply input | Connects to 5.5–27 V battery rail; feeds internal regulators and high-voltage drivers. |
| VSREG | Regulated supply input | Accepts 4.5–5.5 V regulated source for low-noise MCU core supply path. |
| OUT1–OUT15 | Power output terminals | Configurable as high-side, low-side, or half-bridge; each supports PWM, current monitor, and protection reporting. |
| OUT_HS | High-side driver output | Dedicated P-channel driver for external MOSFET gate control with buffered supply and fail-safe pull-down. |
| CANH / CANL | HS-CAN differential pair | Compliant with ISO 11898-2; supports bus fault diagnosis and selective wake-up via RXD_CAN signal. |
| LIN | LIN bus I/O | Single-wire bidirectional interface with integrated transceiver, slew-rate control, and wake-up detection. |
| SPI_MOSI / MISO / SCLK / NSS | Serial peripheral interface | ST SPI 4.0 protocol; enables real-time configuration of all drivers, watchdogs, and ADC channels. |
| WU | Wake-up input | Dedicated pin for external wake event (e.g., door handle sensor); triggers transition from VBAT_standby mode. |
Key Features
| Feature | Design Value |
|---|---|
| Selective wake-up CAN | ISO 11898-6-compliant local wake detection without full bus arbitration - reduces system quiescent current to < 100 µA in standby. |
| Fail-safe low-side block | Two isolated 1 Ω LS switches that forcibly pull down external HS MOSFET gates during thermal or fault events - prevents uncontrolled motor motion. |
| Electro-chromic controller | Dedicated ECV/ECDR outputs with programmable voltage ramp and polarity reversal - enables direct drive of EC glass without external H-bridge. |
| Thermal cluster monitoring | On-die temperature diode + ADC-based thermal mapping across output stages - enables dynamic derating and localized thermal shutdown. |
| Programmable soft-start | Configurable current limit threshold and ramp time for OUT1–6, OUT7, OUT8, and OUT_HS - suppresses inrush current in capacitive or inductive loads. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive door zone driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP MC33883 | Single HS-CAN (no selective wake-up); 8 high-side drivers; no EC glass control; no dual 5 V regulators | Lacks ISO 11898-6 support and electro-chromic interface - unsuitable for EC mirror integration | Select when only basic door latch/window control is required and CAN partial networking is not needed. |
| Infineon TLE9201SG | Single half-bridge (4.5 A); no LIN; no regulators; no SPI configuration - standalone gate driver only | Requires external MCU, CAN/LIN transceivers, and regulators - increases system complexity and footprint | Choose for cost-sensitive designs where integration level is secondary to unit price. |
Compared with MC33883 and TLE9201SG, L99DZ100GPTR delivers higher functional integration (CAN+LIN+regulators+EC control), lower system-level BOM count, and certified selective wake-up - making it optimal for next-gen automotive door ECUs requiring ASIL-B compliance and feature-rich consolidation.

FAQ
What is the difference between L99DZ100G and L99DZ100GP?
L99DZ100GP supports ISO 11898-6:2013 partial networking for selective wake-up via CAN bus activity, while L99DZ100G implements standard HS-CAN (ISO 11898-2/5) without selective wake capability. Both share identical pinout, package, and non-CAN functionality including LIN, regulators, and power outputs.
Does L99DZ100GPTR include internal voltage regulators?
Yes - it integrates two independent 5 V linear regulators: V1 (150 mA) for MCU core supply and V2 (100 mA) for peripherals. Each regulator features undervoltage detection, short-circuit protection, and thermal shutdown, with separate enable/control registers accessible via SPI.
How is electro-chromic glass controlled using this IC?
L99DZ100GPTR provides dedicated ECV (electro-chromic voltage) and ECDR (electro-chromic drive) outputs with programmable polarity reversal, voltage ramp timing, and VS duty-cycle compensation. These outputs directly drive EC glass without external H-bridge or charge pump, enabling precise optical density control.
What protection mechanisms apply to the high-side drivers?
All high-side drivers feature per-channel open-load detection, overcurrent shutdown with thermal expiration, current monitor output (CM), and thermal warning. Outputs OUT1–OUT15 and OUT_HS also support programmable soft-start and PWM-controlled slew rate to limit dv/dt-induced EMI and stress.
