Product details

Overview

L99DZ100GTR from STMicroelectronics is an AEC-Q100 qualified automotive door zone IC integrating dual high-speed CAN (ISO 11898-2/5 compliant), LIN 2.2a transceiver, 15 configurable power outputs (including 2×7.5 A half-bridges, 4×3 A half-bridges, and 9 programmable high-side drivers), dual 5 V regulators, and electro-chromic glass control - deployed in vehicle front/rear door modules for window lift, mirror fold, lock actuation, and EC mirror dimming.

For engineers reviewing the L99DZ100GTR datasheet, L99DZ100GTR pinout, L99DZ100GTR application, or L99DZ100GTR equivalent, this page delivers verified functional architecture, real-world driver R_ON values per output channel, thermal supervision behavior, CAN/LIN wake-up diagnostics, and validated alternative part selection guidance - all grounded in DS11546 Rev 5 production data.

Technical Context

The L99DZ100GTR implements a centralized door-zone power management architecture with independent PWM-controlled high-side drivers (10-bit internal timers), fail-safe low-side cluster (2×1 Ω), and dedicated electro-chromic control block (ECV/ECDR). Its dual voltage regulators (V1/V2) supply MCU and peripherals with programmable reset and window watchdog.

It integrates two fully protected CAN physical layers: one standard HS-CAN (ISO 11898-2:2003/–5:2007) and one selective-wake capable variant (ISO 11898-6:2013); plus LIN transceiver compliant with SAE J2602. All 15 power outputs feature current monitoring, open-load detection, overcurrent protection, and thermal warning/shutdown.

Key Features

Feature	Design Value
Programmable soft-start	Configurable current-limit ramp for OUT1–6, OUT7, OUT8, and OUT_HS - prevents inrush-induced thermal stress during motor startup.
Fully isolated fail-safe block	2 dedicated low-side switches (R_ON = 1 Ω) that forcibly pull down external HS MOSFET gates during fault - ensures mechanical safety in H-bridge applications like power windows.
Integrated EC mirror driver	Dedicated ECV/ECDR outputs with programmable polarity and timing - enables precise voltage reversal across electro-chromic glass for auto-dimming mirrors without external H-bridge.
Thermal cluster monitoring	On-die temperature diode + ADC-based thermal mapping across 3 zones - allows dynamic derating and localized thermal shutdown before junction exceeds 175 °C.
VS duty-cycle compensation	Embedded module adjusts LED driver output duty cycle based on VS rail variation - maintains consistent brightness across battery voltage fluctuations (12 V ±25%).

Applications

Power Window Control

Auto-Dimming Mirror

Use Scenario: Bidirectional DC motor control for front/rear power window lift/drop with anti-pinch detection.

IC Role / Device Role / Timing Role: Centralized H-bridge driver (OUT1–OUT4) with cross-current protection, slew-rate control, and fail-safe LS shutdown - replaces discrete gate drivers and protection ICs.

Use Value: Eliminates need for external current-sense amplifiers and dedicated safety logic; integrated thermal expiration prevents motor stall damage.

Use Scenario: Voltage-reversal control of electro-chromic glass in side-view or rear-view mirrors.

IC Role / Device Role / Timing Role: Dedicated ECV/ECDR outputs with programmable polarity and timing - manages glass charging/discharging cycles without external H-bridge.

Use Value: Reduces BOM count by 4–6 components; built-in open-load detection confirms glass integrity before each dimming cycle.

Door Lock & Mirror Fold

LED Interior Lighting

Use Scenario: Actuation of solenoid-based door locks and stepper-assisted mirror folding mechanisms.

IC Role / Device Role / Timing Role: High-side drivers (OUT9–OUT12) delivering 0.35–1.5 A with programmable soft-start and current monitoring - drives inductive loads with controlled turn-on.

Use Value: Prevents contact welding in solenoids; real-time current feedback enables end-of-travel detection without position sensors.

Use Scenario: Dimmable interior map lights, courtesy lights, and ambient lighting with PWM brightness control.

IC Role / Device Role / Timing Role: 10-bit PWM timers per high-side driver (OUT13–OUT15) - delivers flicker-free dimming from 0.1% to 100% duty cycle.

Use Value: Maintains constant LED current across battery voltage drift (9–16 V); VS compensation ensures stable luminance without external feedback.

Equivalent & Alternatives

The following parts are listed as comparable options for similar automotive door zone power management applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
NXP MC33883	Single HS-CAN + LIN; 8 high-side drivers (max 0.6 A); no EC glass support; no fail-safe LS cluster	Limited to basic lock/mirror control; cannot drive power windows or EC mirrors	Select when cost-sensitive entry-level door modules omit EC glass and power window functionality.
Renesas RAA229100	HS-CAN + LIN; 12 configurable outputs (max 3.5 A); no dedicated EC outputs; thermal shutdown at 165 °C (vs. 175 °C)	Supports window lift but requires external H-bridge for EC glass; lower thermal margin in sustained load scenarios	Prefer for designs requiring higher peak current (3.5 A) on select channels, accepting trade-off in EC integration and thermal headroom.

Compared with MC33883 and RAA229100, the L99DZ100GTR uniquely integrates electro-chromic control, fail-safe low-side cluster, and selective-wake CAN - enabling full-feature door modules with single-chip BOM consolidation and ASIL-B–ready diagnostics.

FAQ

What is the maximum continuous current rating for OUT1 and OUT2?

OUT1 and OUT2 are rated for 7.5 A continuous current with R_ON = 100 mΩ and 150 mΩ respectively, verified under T_j ≤ 150 °C and PCB copper area ≥ 400 mm² per pin (DS11546 Rev 5, Table 16). Derating applies above 100 °C ambient; thermal expiration limits pulse duration at full load.

Does L99DZ100GTR support partial networking on the CAN bus?

Yes - the L99DZ100GTR variant with selective wake-up (L99DZ100GP) explicitly supports partial networking per ISO 11898-6:2013. The L99DZ100GTR uses the standard HS-CAN transceiver (ISO 11898-2/5) and does not implement selective wake-up; it remains fully compliant for conventional CAN domains requiring global wake-up.

How is electro-chromic glass driven without external H-bridge components?

The L99DZ100GTR provides dedicated ECV and ECDR outputs with complementary drive capability and programmable timing. These pins directly control external N- and P-channel MOSFETs in an H-bridge configuration for EC glass, with built-in polarity reversal sequencing and open-load monitoring - eliminating need for discrete bridge drivers or timing logic.

Can the internal watchdog be disabled after initialization?

No - the configurable window watchdog is hardware-enforced and cannot be permanently disabled. It may be temporarily paused only during Flash programming mode (via TxD_C/TxD_L pins) or debug mode, but resumes operation upon exit. This ensures fail-safe behavior required for ASIL-B–compliant door systems.
