Product details
Overview
LM9061M/NOPB from Texas Instruments is a high-side protection controller IC that drives external N-channel MOSFETs in automotive and industrial power distribution systems. It provides lossless overcurrent protection via VDS monitoring, programmable latch-off delay (8–18 ms), 7–26 V supply operation, and clamped +15 V gate drive for robust high-side switching in transmission control units and solenoid drivers.
For engineers reviewing the LM9061M/NOPB datasheet, LM9061M/NOPB pinout, LM9061M/NOPB application, or LM9061M/NOPB equivalent, key selection criteria include its 110 µA normal turnoff sink current, 10 µA latched-off sink current, 1.25 V reference voltage tolerance, SOIC-8 package compatibility, and AEC-Q100 qualification for automotive-grade reliability.
Technical Context
The LM9061M/NOPB implements a charge-pump-based gate driver architecture generating VOUT = VCC + 7 to VCC + 15 V for high-side N-MOSFET control. Its protection circuitry continuously compares VDS across the external MOSFET using a precision comparator with 1.15–1.35 V internal reference and externally programmable threshold via RREF = 15.4 kΩ.
Turnoff behavior is dual-mode: 110 µA sink for normal logic-controlled shutdown (4–10 ms TOFF), and 10 µA sink during overcurrent latch-off (45–140 ms TOFF) to suppress inductive flyback. Delay timing is set by an external capacitor on pin 8, with 5–6.2 V threshold and 2–10 mA discharge current.
Key Specifications

| Latch-Off Sink Current | 5–15 µA - extends turnoff time to 45–140 ms during fault, minimizing dV/dt stress on MOSFET |
| Delay Timer Interval | 8–18 ms - programmable via external capacitor to avoid nuisance tripping during startup surges |
Pinout & Package
LM9061M/NOPB is housed in an SOIC-8 (D) package measuring 4.9 mm × 3.91 mm, optimized for surface-mount assembly and thermal dissipation (RθJA = 150 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| On/Off (Pin 7) | CMOS-compatible enable control | Logic high (≥3.5 V) enables gate drive; logic low (≤1.5 V) initiates gradual turnoff |
| Delay (Pin 8) | Programmable fault delay node | Capacitor-to-ground sets 8–18 ms delay before latch-off activation after VDS overthreshold |

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 |
|---|---|---|---|
| TPS4H160-Q1 | Integrated 40 mΩ high-side FET; no external MOSFET required; higher quiescent current (15 µA vs 5 mA) | Lower-power loads (<5 A); eliminates MOSFET layout complexity but limits max current and thermal design flexibility | Select when board space and BOM count are prioritized over high-current scalability and thermal management control |
| LM5069MMX-2 | Hot-swap controller with current-limiting (not VDS-based); requires external sense resistor; supports 0–100 V input | Board-level power sequencing and inrush control; not suited for direct MOSFET gate drive or inductive load turnoff shaping | Select for upstream power rail protection with precise current regulation, not for high-side MOSFET gate control with inductive transient suppression |
Compared with TPS4H160-Q1 and LM5069MMX-2, LM9061M/NOPB uniquely combines external MOSFET scalability, lossless VDS sensing, and programmable gradual fault turnoff - making it optimal for high-current, inductive automotive actuators where thermal headroom and transient immunity are critical.

FAQ
What is the primary function of the LM9061M/NOPB in a power system?
The LM9061M/NOPB functions as a high-side protection controller that drives and safeguards external N-channel MOSFETs in automotive and industrial power distribution. It provides gate drive voltage above VCC, monitors VDS for lossless overcurrent detection, and executes programmable, gradual turnoff during faults. The LM9061M/NOPB enables robust, efficient high-side switching without sense resistors - critical for solenoid, motor, and relay drivers.
Does the LM9061M/NOPB require an external MOSFET, and why?
Yes, the LM9061M/NOPB requires an external N-channel MOSFET because it is a gate driver controller-not an integrated power switch. Its architecture uses a charge pump to generate gate voltage > VCC, allowing flexible selection of MOSFETs optimized for current, RDS(on), and thermal performance. This design gives designers full control over power stage scalability, thermal management, and cost-unlike monolithic alternatives. The LM9061M/NOPB itself does not conduct load current.
How does the LM9061M/NOPB implement lossless overcurrent protection?
The LM9061M/NOPB implements lossless overcurrent protection by continuously comparing the drain-to-source voltage (VDS) of the external MOSFET against a user-programmed threshold-eliminating the need for a power-dissipating sense resistor. It uses a precision comparator with a 1.15–1.35 V internal reference and external resistive divider (via IREF and RTHRESHOLD) to set the trip point. When VDS exceeds this threshold due to overload or short circuit, the LM9061M/NOPB latches off the gate drive with a 10 µA sink current for controlled turnoff.
What is the role of the Delay pin (Pin 8) on the LM9061M/NOPB?
The Delay pin (Pin 8) on the LM9061M/NOPB sets the time interval between overcurrent detection and latched gate turnoff. An external capacitor connected from Pin 8 to ground establishes a programmable delay of 8–18 ms, preventing nuisance tripping during inrush currents or transient overloads. Internally, the pin sources 6.74–15.44 µA to charge the capacitor and triggers latch-off when the voltage reaches 5–6.2 V. This feature ensures reliable operation in applications like solenoid actuation where peak currents exceed steady-state values.
Is the LM9061M/NOPB qualified for automotive applications, and what standards does it meet?
Yes, the LM9061M/NOPB is AEC-Q100 qualified for automotive applications. It meets HBM ESD classification Level 2 (±2000 V) and CDM ESD classification Level C4B (±1000 V), and operates across −40°C to +125°C ambient temperature. Its 60 V transient tolerance, overvoltage shutdown at VCC > 30 V, and robust pin protection (−25 V to +60 V) make it suitable for engine control units, transmission control units, and other safety-critical automotive subsystems. The LM9061M/NOPB is explicitly designed for automotive-grade reliability.
