Product details
Overview
LM5060Q1MM/NOPB from Texas Instruments is an automotive-grade high-side N-channel MOSFET protection controller for 5.5 V–65 V input systems, featuring programmable UVLO (1.6 V threshold), OVP (2.0 V threshold), and fault timer via external capacitor; delivers 24 µA gate charge current and 80 mA fault discharge current; used in automotive body electronics power distribution.
For engineers reviewing the LM5060Q1MM/NOPB datasheet, LM5060Q1MM/NOPB pinout, LM5060Q1MM/NOPB application, or LM5060Q1MM/NOPB equivalent, key selection criteria include VIN operating range, GATE drive capability, nPGD status signaling, fault latching behavior, and AEC-Q100 qualification for safety-critical automotive use.
Technical Context
The LM5060Q1MM/NOPB implements dual-stage fault detection: first monitors VGS rise during startup using a 5 V comparator with 6 µA timer charge, then transitions to VDS monitoring with 11 µA timer charge after VGS exceeds threshold; fault latching occurs only when TIMER pin voltage reaches 2.0 V and persists until EN/UVLO/VIN toggles.
It integrates a charge-pump-based gate driver delivering ~12 V above VIN under normal operation and clamping at 16.8 V above OUT; supports redundant enable via UVLO pin as second control input; nPGD is open-drain active-low, sinking up to 5 mA with <205 mV low-level voltage at 2 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 5.5 V to 65 V - supports wide automotive battery and industrial supply rails without external regulation |
| Quiescent Current | <15 µA in disabled mode - enables ultra-low-power standby in always-on vehicle modules |
| GATE Drive | 24 µA sourcing current - provides controlled dV/dt for safe hot-swap into capacitive loads |
| Fault Discharge | 80 mA sink current - ensures rapid MOSFET turn-off during overcurrent or overvoltage events |
| OVP Threshold | 2.0 V (typical) on OVP pin - sets input overvoltage shutdown at system level via resistor divider |
| UVLO Threshold | 1.6 V (typical) on UVLO pin - enables dual-enable redundancy and brownout protection |
| nPGD Output | Open-drain, active-low - signals MOSFET ON status (low = OK) with <205 mV VOL at 2 mA load |
| Operating Temp | –40°C to +125°C - qualified per AEC-Q100 Grade 1 for under-hood automotive environments |
Pinout & Package
LM5060Q1MM/NOPB uses a 10-pin VSSOP package (3.00 mm × 3.00 mm), thermally optimized for surface-mount power distribution applications with exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SENSE | VDS fault sense input | 16 µA constant-current sink sets voltage threshold for overcurrent detection relative to OUT |
| VIN | Main supply input | 5.5–65 V input rail connection; powers internal bias circuits and triggers POR at >5.1 V |
| OVP | Overvoltage monitor input | Resistor-divider input for adjustable OVP trip; 2.0 V threshold disables GATE but does not latch |
| UVLO | Undervoltage lockout input | Second enable path; 1.6 V threshold releases GATE pull-down when EN is high |
| EN | Primary enable input | Logic-level control: <0.8 V disables (9 µA quiescent), >2.0 V enables bias and UVLO comparator |
| GND | Signal and power ground | Common reference for all analog comparators, timers, and output drivers |
| TIMER | Fault timing capacitor node | Charged by 6 µA (startup) or 11 µA (run); 2.0 V threshold triggers latched fault shutdown |
| nPGD | Power good status output | Open-drain indicator: low = MOSFET fully on and VDS normal (SENSE < OUT) |
| OUT | Output voltage sense | Connected to MOSFET source; used with SENSE to detect VDS fault condition |
| GATE | MOSFET gate driver output | Charge-pump-driven 24 µA source; clamped at 16.8 V above OUT; sinks 80 mA during fault |
Key Features
| Feature | Design Value |
|---|---|
| Functional Safety Capable | Documentation available for ISO 26262 ASIL-B system integration including FIT rate and failure mode analysis |
| Controlled Output Rise Time | Programmable via external GATE-to-GND capacitor to limit inrush into large bulk capacitance |
| Redundant Enable Architecture | UVLO pin serves as independent second enable input, supporting dual-channel safety monitoring |
| Three-Stage Fault Timing | Separate timer phases for VGS startup (6 µA), VDS transition (11 µA), and continuous overcurrent (11 µA) |
| Immediate OVP Recovery | Auto-restart after overvoltage clears - no manual reset required once OVP pin falls below 1.76 V |
| Latched Fault Protection | MOSFET remains off after TIMER ≥2.0 V until EN, UVLO, or VIN toggles - prevents uncontrolled re-engagement |
Applications
| Automotive Front Lighting Control | Industrial PLC Power Backplane |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side protection controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5069Q1MMX/NOPB | Integrated 100 mΩ FET; fixed 1.25 V OVP; no UVLO pin; 2.5 ms default fault timer | Lower BOM count for space-constrained designs; lacks dual-enable redundancy | Select when integrated FET suffices and UVLO redundancy is unnecessary |
| TPS25940LARVRR | 40 V max VIN; digital I²C interface; programmable current limit; no OVP/UVLO inputs | Enables real-time telemetry and dynamic configuration; requires MCU coordination | Select when telemetry, precise current limiting, and smaller footprint outweigh analog simplicity |
Compared with LM5060Q1MM/NOPB, LM5069Q1MMX/NOPB reduces external component count but sacrifices UVLO-based safety redundancy, while TPS25940LARVRR adds digital configurability at the cost of higher design complexity and lower voltage rating - making LM5060Q1MM/NOPB optimal for analog-safety-first automotive power distribution.

FAQ
What is the purpose of the TIMER pin on the LM5060Q1MM/NOPB?
The TIMER pin on the LM5060Q1MM/NOPB sets the fault detection delay time using an external capacitor. It charges at 6 µA during startup and 11 µA during normal operation; reaching 2.0 V triggers latched MOSFET shutdown. This allows precise tuning of response time for inrush control and overcurrent protection without software intervention.
How does the LM5060Q1MM/NOPB implement dual-enable safety redundancy?
The LM5060Q1MM/NOPB implements dual-enable safety redundancy by allowing the UVLO pin to function as a second independent enable input. When EN is high, the UVLO comparator activates; a voltage >1.6 V releases the GATE pull-down. This enables two physically separate control paths - critical for ASIL-B system architectures where single-point failures must be mitigated.
Does the LM5060Q1MM/NOPB support immediate restart after overvoltage events?
Yes, the LM5060Q1MM/NOPB supports immediate restart after overvoltage events. When the OVP pin voltage falls below its hysteresis threshold (~1.76 V), the GATE driver resumes normal operation without requiring an EN or UVLO toggle. This behavior enables automatic recovery from transient load-dump spikes common in automotive 12 V systems.
What is the maximum gate drive voltage provided by the LM5060Q1MM/NOPB?
The LM5060Q1MM/NOPB provides a maximum gate drive voltage of 16.8 V above the OUT pin, enforced by an internal zener clamp. Under normal operation, the GATE pin voltage is typically 12 V above VIN. This ensures robust enhancement of standard N-channel MOSFETs while preventing gate oxide overstress during high-VIN conditions.
Is the LM5060Q1MM/NOPB qualified for automotive applications?
Yes, the LM5060Q1MM/NOPB is explicitly qualified per AEC-Q100 Grade 1 (–40°C to +125°C) and designated as "automotive grade" in TI's official documentation. It includes functional safety documentation to support ISO 26262 system-level development and is widely deployed in automotive body electronics and power distribution modules.
