Product details
Overview
LM5060Q1MMX/NOPB from Texas Instruments is an AEC-Q100 qualified high-side N-channel MOSFET protection controller for automotive and industrial power distribution. It provides programmable UVLO (1.6 V threshold), OVP (2.0 V threshold), and fault detection delay via external TIMER capacitor, with <15 µA quiescent current in disabled mode and 24 µA gate charge current for controlled output rise time into capacitive loads.
For engineers reviewing the LM5060Q1MMX/NOPB datasheet, LM5060Q1MMX/NOPB pinout, LM5060Q1MMX/NOPB application, or LM5060Q1MMX/NOPB equivalent, key selection criteria include its 5.5–65 V input range, active-low open-drain nPGD status output, charge-pump gate drive supporting up to 16.8 V VGS clamp, and latch-off behavior during sustained VDS or VGS faults - all in a 10-pin VSSOP package rated for –40°C to 125°C operation.
Technical Context
The LM5060Q1MMX/NOPB implements dual-stage fault detection: a VGS comparator (5 V threshold) validates MOSFET turn-on before enabling full VDS monitoring, while the SENSE–OUT differential comparator detects overcurrent via external sense resistor. Its TIMER pin uses three distinct current sources (6 µA startup, 11 µA post-VGS, 6 mA reset) to manage fault timing across start-up, transition, and steady-state conditions.
Control logic integrates safety redundancy via dual enable inputs (EN and UVLO), where UVLO serves as a second functional enable with hysteresis (180 mV typical). The GATE driver combines constant-current sourcing (24 µA) with dual-sink capability: 2.2 mA for normal disable and 80 mA for fault latching - both referenced to OUT, not GND, enabling true high-side operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 5.5 V to 65 V - supports 12 V/24 V/48 V automotive and industrial bus systems without external regulators. |
| Quiescent Current (Disabled) | <15 µA - enables always-on systems with minimal battery drain during sleep modes. |
| GATE Drive Current | 24 µA sourcing (typical) - delivers controlled dV/dt for safe hot-plug into large capacitive loads (e.g., ECUs, infotainment). |
| VGS Fault Threshold | 5 V (typical) - ensures MOSFET fully enhances before enabling VDS monitoring, preventing false overcurrent trips. |
| OVP Threshold | 2.0 V (rising), 1.76 V (falling) - adjustable via external divider; immediate restart after overvoltage clears. |
| nPGD Output | Active-low open-drain - sinks 5 mA max; asserts low when SENSE > OUT (i.e., no fault), simplifying system-level status polling. |
| Operating Temperature | –40°C to +125°C - meets AEC-Q100 Grade 1 requirements for under-hood and chassis-mounted applications. |
Pinout & Package
LM5060Q1MMX/NOPB is housed in a 10-pin VSSOP package (3.00 mm × 3.00 mm body size) with exposed thermal pad for enhanced power dissipation in high-current applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SENSE | VDS fault sense input | 16 µA constant-current sink sets overcurrent threshold by resistor-to-ground; compares against OUT to detect MOSFET conduction loss. |
| VIN | Main supply input | 5.5–65 V operating range; powers internal bias circuitry; POR activates above 5.1 V. |
| OVP | Overvoltage monitor input | Resistor-divider input; triggers 9.6 µs fast GATE discharge when voltage exceeds 2.0 V (no latch). |
| UVLO | Redundant enable input | 5.5 µA pull-down sink; 1.6 V threshold with 180 mV hysteresis; doubles as safety-critical secondary enable. |
| EN | Primary enable input | 6 µA pull-down sink; 2.0 V high-threshold enables bias and UVLO comparator; disables GATE drive below 0.8 V. |
| GND | Power ground reference | Common return for all analog and digital functions; connects to PCB ground plane for noise immunity. |
| TIMER | Fault timing capacitor node | Accepts external capacitor to program VGS/VDS fault delays; charges at 6 µA (startup) or 11 µA (post-VGS); resets at 6 mA. |
| nPGD | Power good status output | Open-drain output; low = healthy (SENSE < OUT), high = fault or unpowered; requires external pull-up. |
| OUT | Output rail sense point | Connects to MOSFET source; used with SENSE to measure VDS; referenced for GATE clamp and nPGD logic. |
| GATE | MOSFET gate driver | Charge-pump output clamped to 16.8 V above OUT; sources 24 µA, sinks 2.2 mA (normal) or 80 mA (fault). |
Key Features
| Feature | Design Value |
|---|---|
| Functional Safety Capability | Documentation support available per ISO 26262; dual enable (EN + UVLO) enables ASIL-B/C system-level redundancy design. |
| Programmable Fault Timing | Single external capacitor configures three independent delay intervals: VGS startup, VDS transition, and continuous overcurrent. |
| Controlled Output Rise Time | Constant-current GATE drive + optional external gate capacitance enables precise dV/dt control for hot-swap compliance. |
| High-Side N-Channel Support | Charge-pump gate driver eliminates need for P-channel MOSFET or level-shifting, reducing conduction losses and board space. |
| Latched Fault Protection | MOSFET remains off after fault until EN, UVLO, or VIN toggles - prevents automatic retry into persistent short-circuit conditions. |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Power Distribution |

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 | Includes integrated 100 mΩ current-sense resistor and I²C interface; higher quiescent current (45 µA vs. 15 µA). | Used where digital telemetry and precise current measurement are required; not suitable for ultra-low-power always-on systems. | Select LM5069Q1MMX/NOPB when system-level current monitoring and programmable trip thresholds via I²C are needed. |
| TPS26631RGER | Integrated 80 mΩ FET; fixed 2.7 V to 60 V range; no UVLO redundancy or TIMER-programmable delays. | Targeted at space-constrained designs where external MOSFET is undesirable; lacks dual-enable safety architecture. | Choose TPS26631RGER for simplified layout and lower BOM count where AEC-Q100 qualification and functional safety documentation are not mandatory. |
Compared with LM5060Q1MMX/NOPB, LM5069Q1MMX/NOPB adds telemetry but increases standby power, while TPS26631RGER reduces component count at the cost of design flexibility and safety features - making LM5060Q1MMX/NOPB optimal for automotive-grade systems requiring configurable timing, dual enable, and minimal quiescent current.

FAQ
What is the purpose of the UVLO pin on the LM5060Q1MMX/NOPB?
The UVLO pin on the LM5060Q1MMX/NOPB serves as a secondary enable input with a 1.6 V threshold and 180 mV hysteresis, providing functional safety redundancy. When pulled high (≥1.6 V), it releases the GATE pull-down and allows output ramp-up - enabling use in ASIL-B/C systems where dual independent enables are required. In open-circuit condition, its 5.5 µA internal sink ensures reliable low state.
How does the LM5060Q1MMX/NOPB implement fault detection and latching?
The LM5060Q1MMX/NOPB detects faults through two comparators: VGS status (5 V threshold) during startup and VDS (SENSE–OUT) during operation. If TIMER pin voltage reaches 2.0 V due to sustained fault, the device latches GATE off using 80 mA sink current. Recovery requires toggling EN, UVLO, or VIN - preventing automatic retry into persistent faults and enhancing system reliability.
Can the LM5060Q1MMX/NOPB drive a P-channel MOSFET?
No, the LM5060Q1MMX/NOPB is specifically designed to drive high-side N-channel MOSFETs using its charge-pump gate driver, which generates a voltage ~16.8 V above the OUT pin. Driving a P-channel MOSFET would require inverted logic and different gate referencing - functionality not supported by the LM5060Q1MMX/NOPB's architecture or pinout.
What is the role of the TIMER capacitor in the LM5060Q1MMX/NOPB application?
The external TIMER capacitor on the LM5060Q1MMX/NOPB sets three distinct fault timing intervals: initial VGS fault delay (6 µA charge), post-VGS VDS transition delay (11 µA charge), and continuous overcurrent delay (11 µA charge). It is discharged at 6 mA during normal operation or fault reset, enabling precise control of inrush management and fault response without additional ICs.
Does the LM5060Q1MMX/NOPB support reverse-battery protection?
The LM5060Q1MMX/NOPB itself does not provide reverse-battery protection; however, its absolute maximum ratings allow –0.3 V on SENSE and OUT pins (with current limited to <–25 mA), and –1 V on EN/UVLO/OVP pins under reverse-battery conditions. System-level reverse protection must be implemented externally - e.g., using a series Schottky diode or dedicated reverse-polarity IC - as the LM5060Q1MMX/NOPB is not rated to block reverse voltage.
