Product details

Overview

L99PM60JTR from STMicroelectronics is an automotive power management IC integrating a 5 V/100 mA low-dropout regulator, LIN 2.1 transceiver (SAE J2602 compliant), two high-side drivers (R_DS(on) = 7 Ω), two low-side drivers (R_DS(on) = 2 Ω), and ST SPI interface for diagnostics and mode control - deployed in door zone ECUs and body control modules.

For engineers reviewing the L99PM60JTR datasheet, L99PM60JTR pinout, L99PM60JTR application, or L99PM60JTR equivalent, key selection criteria include ultra-low standby current (7 µA VBAT-standby), programmable reset threshold (4.6 V / 3.5 V), window watchdog, fail-safe output configuration, and direct-drive capability for high-side loads without external gate drivers.

Technical Context

The device implements a dual-mode power architecture with Active, Flash, V1-standby, and VBAT-standby states, enabling precise energy management in battery-constrained automotive nodes. Its LIN transceiver supports standard and high-speed Flash modes up to 100 Kbit/s and includes LIN wake-up detection with configurable response timing.

ST SPI provides full register-level access to status, control, and diagnostic data-including real-time driver fault reporting, VS supply monitoring, temperature warning flags, and thermal shutdown events-while the window watchdog enforces system-level safety compliance via configurable timeout and recovery behavior.

Key Specifications

Parameter	Value and Actual Design Meaning
Regulator Output	5 V ±2%, 100 mA continuous - powers microcontroller core logic and peripherals without bulk electrolytic capacitor (only 220 nF ceramic required).
Standby Current	7 µA (VBAT-standby), 45 µA (V1-standby) - enables multi-year battery life in always-on automotive modules.
LIN Compliance	LIN 2.1 + SAE J2602 - ensures interoperability with automotive LIN networks including slave node addressing and error handling.
Driver R_DS(on)	7 Ω (HS), 2 Ω (LS) - supports direct drive of LEDs, Hall sensors, and relays without external FETs or level shifters.
Reset Threshold	Programmable at 4.6 V or 3.5 V - allows flexible brown-out detection aligned with MCU supply requirements.
Watchdog Type	Window watchdog - prevents both early and late refreshes, eliminating silent lockup or premature resets in safety-critical firmware.
Thermal Protection	Temperature warning flag + thermal shutdown - provides early fault indication before catastrophic junction overheating occurs.

Pinout & Package

Package: PowerSSO-16 (exposed pad, thermally enhanced SO-16 variant with wettable flanks).

Pin/Terminal	Circuit Role	Design Meaning
V1	Regulated 5 V output	Supplies MCU and peripheral logic; short-circuit protected with foldback current limiting.
VS	Main battery input (6–27 V)	Primary power source; monitored for over/undervoltage and used for power-on reset generation.
VBAT	Battery backup input	Enables VBAT-standby mode; powers internal logic during main supply loss.
LIN	LIN bus I/O	Single-wire bidirectional LIN physical layer interface with integrated pull-up and slew-rate control.
TXD/RXD	SPI data interface	Asynchronous serial interface for diagnostics and configuration (not LIN signals - dedicated to ST SPI).
CSN	SPI chip select	Active-low enable for SPI communication; also controls entry into LIN Flash programming mode.
OUT1	Configurable fail-safe output	Programmable as high-side or low-side driver; asserts on critical faults (e.g., thermal shutdown, watchdog timeout).
REL1/REL2	Low-side driver outputs	Ground-switched outputs with current sensing and short-circuit protection; support relay or solenoid control.
HSD1/HSD2	High-side driver outputs	Direct-drive capable outputs with built-in charge pump; eliminate need for external high-side gate drivers.
NRESET	Open-drain reset output	Active-low reset signal synchronized to V1 regulation status and programmable threshold detection.

Key Features

Feature	Design Value
No electrolytic capacitor required	220 nF ceramic suffices on V1 output - reduces board area, improves lifetime reliability, and eliminates capacitor aging concerns.
Direct high-side drive	Integrated charge pump enables true high-side switching without external components - simplifies PCB layout and reduces BOM count.
Configurable fail-safe output	OUT1 can be set as high- or low-side driver via SPI - adapts to diverse load topologies (e.g., LED anode/cathode switching).
LIN Flash mode	100 Kbit/s high-speed programming mode - enables in-vehicle firmware updates over LIN without requiring additional debug interfaces.
VS monitoring & temp sensing	On-chip voltage and temperature measurement - provides real-time health telemetry for predictive diagnostics and thermal derating.

Equivalent & Alternatives

The following parts are listed as comparable options for similar automotive power management and LIN interface applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLE9261-2QX	Higher current regulator (150 mA), integrated CAN FD interface instead of LIN, no direct high-side drive	Targeted at gateway modules requiring CAN connectivity; lacks LIN-specific features like Flash mode	Select when CAN FD backbone integration is required and LIN is not needed
MC33816	Includes 3.3 V/200 mA regulator + 5 V/100 mA regulator, LIN 2.2a compliant, no integrated high-side drivers	Designed for dual-rail MCU systems; requires external high-side switches for actuator control	Select when dual-voltage regulation is mandatory and external driver flexibility is preferred

Compared with TLE9261-2QX and MC33816, the L99PM60JTR uniquely combines LIN Flash programming, direct high-side drive, and ultra-low VBAT-standby current - making it optimal for cost-sensitive, space-constrained LIN slave nodes where actuator integration and long-term battery retention are critical.

FAQ

What LIN protocol versions does the L99PM60JTR support?

The L99PM60JTR is fully compliant with LIN 2.1 and SAE J2602 standards, including support for standard data rates (up to 20 Kbit/s) and high-speed Flash mode (up to 100 Kbit/s). It implements all mandatory LIN frame structures, checksum models, and error handling per specification - no software stack modification is required for interoperability.

Does the L99PM60JTR require external components for its 5 V regulator?

No external electrolytic capacitor is required for the 5 V regulator - only a 220 nF ceramic capacitor on the V1 output is needed for stability. The internal compensation and low-noise design eliminate the need for bulk capacitance, reducing board space and improving long-term reliability versus aluminum or tantalum alternatives.

How is fail-safe behavior configured on the L99PM60JTR?

Fail-safe behavior is configured via ST SPI registers: OUT1 can be set as high-side or low-side driver, and activation conditions (e.g., thermal shutdown, watchdog timeout, VS undervoltage) are individually maskable. The fail-safe output asserts within 10 µs of fault detection and remains active until cleared via SPI command or power cycle.

Can the L99PM60JTR drive inductive loads directly?

Yes - both high-side (HSD1/HSD2) and low-side (REL1/REL2) drivers include integrated clamp diodes and current-limiting circuitry rated for inductive loads such as relays and solenoids. Each output supports continuous 350 mA and peak 1 A, with automatic short-circuit recovery and thermal foldback to prevent latch-up.
