Product details
Overview
L99PM62XP from STMicroelectronics is an automotive power management IC integrating dual 5V 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 ST SPI interface - deployed in door zone and body control modules for stable microcontroller and peripheral supply with programmable wake-up and fail-safe operation.
For engineers reviewing the L99PM62XP datasheet, L99PM62XP pinout, L99PM62XP application, or L99PM62XP equivalent, key selection considerations include standby current (<10 µA), regulator output capability (V1: 150 mA, V2: 300 mA), CAN partial networking support, cyclic contact monitoring, and thermal shutdown at 175 °C.
Technical Context
The device implements a multi-mode power architecture with five distinct operating states (Active, Flash, V1 Standby, VBAT Standby, Fail-Safe), each governed by configurable voltage thresholds and wake-up sources including LIN/CAN bus activity, dedicated WU1–WU3 inputs, and periodic timer interrupts. Local failure diagnosis is embedded across all driver channels and communication layers.
Its HS CAN transceiver supports receive-only and looping modes alongside local/bus failure detection, while the LIN transceiver complies with SAE J2602 and includes integrated pull-up control (LINPU). The ST SPI 3.0 interface enables full register-level control of mode transitions, watchdog timing, reset behavior, and diagnostic status reporting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V1 Regulator Output | 5.0 V ±2%, 150 mA max - powers MCU core logic with no external electrolytic capacitor required. |
| V2 Regulator Output | 5.0 V ±2%, 300 mA max - supplies sensors/peripherals; supports increased current via external boost configuration. |
| Standby Quiescent Current | <10 µA in VBAT standby - enables ultra-low-power battery monitoring over extended vehicle-off periods. |
| CAN Transceiver Compliance | ISO 11898-2/-5 and SAE J2284 - ensures interoperability in 12 V automotive networks with partial networking support. |
| LIN Transceiver Compliance | LIN 2.1 and SAE J2602 - provides robust single-wire communication for body electronics with integrated wake-up detection. |
| High-Side Drivers | 5 channels, fully protected (overcurrent, overtemperature, load dump) - drives resistive/inductive loads up to 1.5 A peak per channel. |
| Op-Amp Performance | 2 × rail-to-rail output (VS), low-voltage input (down to 0.3 V), gain bandwidth product 1.2 MHz - suitable for sensor signal conditioning in 5 V domains. |

| NRESET | Reset output | Open-drain active-low reset signal generated on power-on, undervoltage, or watchdog timeout. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable window watchdog | Configurable timeout (1.6 ms to 10 s) with independent enable/disable per mode; prevents MCU lockup without false triggers. |
| Fail-safe output (FSO) | Dedicated pin asserting during critical faults (thermal shutdown, regulator failure, SPI communication loss); enables system-level safe state entry. |
| 3-channel contact monitoring | Programmable cyclic sense functionality detects switch closures (e.g., door ajar, trunk open) with automatic debouncing and status reporting via SPI. |
| Periodic system wake-up | Internal 4-timer subsystem generates precise wake-up events (10 ms to 256 s intervals) without MCU involvement - extends battery life in always-on monitoring. |
| Thermal protection | Temperature warning flag at 150 °C and hard thermal shutdown at 175 °C; both reported via SPI status registers and FSO assertion. |
Applications

Use Value: Eliminates need for external current-sense amplifiers and discrete protection ICs; thermal shutdown at 175 °C prevents catastrophic failure under sustained overload. |
Use Scenario: Motorized seat position adjustment with memory, heating, and occupancy sensing. IC Role / Device Role / Timing Role: Sensor interface and actuator driver - conditions seat sensor signals using rail-to-rail op-amps and drives seat motors via PWM-controlled high-side outputs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive power management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE9262-2QX | Single 5 V regulator (250 mA), no LIN transceiver, CAN compliant only to ISO 11898-2 (not -5), no op-amps | Targeted at simpler ECU designs where LIN is not required and analog signal conditioning is handled externally | Choose when CAN-only communication suffices and cost-sensitive BOM optimization is prioritized over integration density |
| MC33816 | Includes SPI-configurable watchdog and reset, but lacks integrated op-amps and contact monitoring; regulator outputs are 3.3 V/5 V (not dual 5 V) | Designed for engine control and transmission modules requiring higher temperature grade (–40 °C to +150 °C ambient) | Prefer for under-hood applications needing extended temperature operation, accepting reduced analog integration |
Compared with TLE9262-2QX and MC33816, L99PM62XP uniquely combines dual 5 V regulators, LIN+CAN PHY, op-amps, and contact monitoring in one PowerSSO-36 package - making it optimal for body electronics where space, feature count, and ultra-low standby current are critical.

FAQ
Does L99PM62XP support partial networking on HS CAN?
Yes, the HS CAN transceiver supports partial networking per ISO 11898-5, enabling selective node wake-up while keeping others in low-power sleep. This is implemented via configurable CAN receive-only mode and local wake-up detection, allowing targeted communication without full bus activation.
What is the minimum input voltage required for V1 regulator startup?
V1 regulator starts regulating when VS reaches 5.5 V (typical), with guaranteed operation from 6.0 V to 27 V. Below 5.5 V, V1 enters undervoltage lockout and asserts NRESET; the regulator resumes normal output once VS exceeds the hysteresis threshold (typically 5.7 V).
How many independent PWM channels does L99PM62XP provide for high-side drivers?
L99PM62XP integrates four internal PWM timers that can be assigned to any of the five high-side outputs (OUT_HS1–5) via SPI configuration. Each timer supports programmable frequency (100 Hz–20 kHz) and duty cycle (0–100%), enabling independent motor speed or LED dimming control without MCU intervention.
Is external capacitor required for stability on V1 or V2 regulator outputs?
No electrolytic capacitor is required on either V1 or V2 outputs due to internal compensation and optimized loop response. The datasheet specifies use of only 1 µF ceramic capacitors (X7R, 10 V rating) per regulator output for high-frequency decoupling - simplifying layout and improving reliability versus traditional electrolytic solutions.
