Product details
Overview
L99PM62XP from STMicroelectronics is a highly integrated automotive power management IC designed for body control modules and door zone ECUs. It integrates two 5V LDO regulators (V1/V2), LIN 2.1 and HS CAN transceivers (ISO 11898-2/-5, SAE J2284), five protected high-side drivers, two low-side drivers, two rail-to-rail op-amps, and an ST SPI 3.0 interface - enabling full system power, communication, and actuation control in a single PowerSSO-36 package.
For engineers reviewing the L99PM62XP datasheet, L99PM62XP pinout, L99PM62XP application, or L99PM62XP equivalent, this device serves as a system basis chip (SBC) with programmable standby modes, fail-safe outputs, cyclic contact monitoring, and diagnostic-ready architecture - critical for automotive ECU design requiring ASIL-B–aware power sequencing, bus wake-up, and driver-level protection.
Technical Context
The L99PM62XP implements a dual-regulator architecture: V1 (5V/150mA) supplies microcontrollers with ultra-low quiescent current (25µA in V1 standby), while V2 (5V/300mA) powers peripherals and supports increased output current capability via external capacitor configuration. Both regulators feature overvoltage/undervoltage detection and thermal shutdown.
Its communication subsystem includes independent LIN and HS CAN physical layers - the LIN transceiver complies with SAE J2602 and supports local wake-up; the CAN transceiver supports partial networking, receive-only mode, and bus failure diagnosis. All functions are controlled and monitored via a dedicated ST SPI 3.0 interface with global status and configurable registers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V1 Regulator Output | 5.0V ±2%, 150mA max - powers MCU core with 25µA standby IQ and no electrolytic capacitor required. |
| V2 Regulator Output | 5.0V ±2%, 300mA max - supplies sensors/peripherals; supports higher current via external capacitor on V2OUT. |
| LIN Transceiver | LIN 2.1 & SAE J2602 compliant - enables bidirectional communication and wake-up from sleep at 20kbit/s. |
| HS CAN Transceiver | ISO 11898-2/-5 & SAE J2284 compliant - supports 1Mbps operation, partial networking, and local/bus failure diagnosis. |
| High-Side Drivers | 5 fully protected channels (OUT_HS, OUT1–OUT4) - each with short-circuit, overtemperature, and open-load detection. |
| Low-Side Drivers | 2 active zener-clamped outputs (REL1, REL2) - optimized for relay coil driving with fast demagnetization. |
| Op-Amps | 2 rail-to-rail output (VS), low-voltage input amplifiers - usable down to 2.7V supply, gain-bandwidth 1.5MHz. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive system basis chip applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP MC33816 | Single 5V regulator (200mA), no integrated op-amps, LIN-only (no HS CAN), different SPI register map. | Limited to LIN-based nodes; lacks CAN gateway capability and analog sensing integration. | Choose when CAN is not required and cost sensitivity outweighs integration benefits. |
| Infineon TLE9471-3ES | Higher current regulators (VCC1=5V/500mA, VCC2=3.3V/200mA), CAN FD support, no LIN, different pinout and fault reporting. | Targets next-gen CAN FD gateways; incompatible with legacy LIN subsystems and existing PCB layouts. | Prefer for new CAN FD designs needing >300mA V2 and 3.3V auxiliary rail - not drop-in compatible. |
Compared with MC33816 and TLE9471-3ES, the L99PM62XP uniquely balances LIN+CAN dual-bus support, integrated op-amps for sensor conditioning, and proven qualification for body electronics - making it optimal for cost-sensitive, mixed-protocol automotive ECUs requiring minimal external components.

FAQ
What is the maximum ambient temperature rating for continuous operation?
The L99PM62XP is qualified for continuous operation up to +105°C ambient temperature under specified electrical conditions, with junction temperature limited to +150°C. Thermal shutdown activates at +165°C junction, and temperature warning asserts at +145°C - both detectable via SPI status registers for proactive thermal management.
Does the device support simultaneous LIN and CAN communication?
Yes - the L99PM62XP operates LIN and HS CAN physical layers independently and concurrently. Its dual-bus architecture allows simultaneous message transmission/reception on both buses, with separate TX/RX pins and independent wake-up sources (WUx for LIN, CANH/CANL for CAN), enabling robust multi-network ECU designs.
How is the reset generator configured for undervoltage detection?
The reset generator is programmable via SPI: V1 undervoltage threshold is fixed at 4.5V ±2%, while V2 threshold can be set to 4.5V or 4.25V via configuration register bit RST_V2TH. Reset pulse width is 20ms (min), and NRESET is an open-drain output pulled low during fault or startup until regulation stabilizes.
Can the high-side drivers be PWM-controlled without external timers?
Yes - the L99PM62XP includes four internal PWM timers that directly drive OUT_HS and OUT1–OUT4. Duty cycle, frequency (10Hz–20kHz), and dead-time are configurable via SPI registers, eliminating need for MCU timer resources or external PWM generators in motor or LED dimming applications.
