Product details
Overview
MP2410GJE-Z from Monolithic Power Systems is a 24V, 2A, synchronous step-down LED driver IC with integrated high-side MOSFET (100mΩ) and low-side synchronous rectifier (80mΩ), operating at fixed 1MHz switching frequency and supporting deep analog dimming via EN/DIM pin. It delivers stable white LED current in handheld flashlights and infrared illumination systems with inherent open-LED and short-circuit protection.
For engineers reviewing the MP2410GJE-Z datasheet, MP2410GJE-Z pinout, MP2410GJE-Z application, or MP2410GJE-Z equivalent, key selection criteria include its 100mV feedback reference, NTC-based thermal foldback, 2A continuous output capability, and TSOT23-8 package compatibility with space-constrained portable lighting designs.
Technical Context
The MP2410GJE-Z implements peak-current-mode control with internal error amplifier comparing FB voltage to a precision 100mV reference, generating COMP voltage to regulate high-side switch conduction time. Its fixed 1MHz oscillator enables compact magnetics and low output ripple in battery-powered LED systems.
It integrates dual protection logic: cycle-by-cycle current limiting (5.5A typical OCP threshold) and fault-triggered hiccup-mode restart (2.4ms timer), while NTC pin monitors ambient temperature via external thermistor to dynamically scale LED current before thermal shutdown at 150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.2V to 24V - supports 12V/24V industrial rails and Li-ion battery stacks without pre-regulation. |
| Output Current | Up to 2A continuous - sufficient for multi-string white or IR LED arrays in flashlight and sensing applications. |
| Switching Frequency | Fixed 1MHz - enables use of sub-5μH inductors and reduces EMI filtering burden in portable designs. |
| Feedback Reference | 100mV ±7mV - low-voltage reference minimizes sense resistor power loss (e.g., 50mΩ for 2A output). |
| Internal MOSFET RDS(ON) | High-side: 100mΩ typ @ 5V; Low-side: 80mΩ typ @ 5V - enables >97% efficiency at full load with minimal thermal derating. |
| Dimming Interface | Analog dimming via EN/DIM pin (0.7V–1.44V range) - provides linear LED current control without PWM noise or EMI spikes. |
| Thermal Protection | NTC input + 150°C junction thermal shutdown with 60°C hysteresis - ensures safe operation under sustained ambient heat or LED overdrive. |
Pinout & Package
MP2410GJE-Z is housed in a thermally enhanced TSOT23-8 package (2.9mm × 1.6mm × 0.85mm), optimized for high-power density LED driver layouts with exposed pad for improved heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 6) | Power and signal reference ground | Primary return path for LED current, SW node, and internal bias - requires low-impedance PCB pour beneath exposed pad. |
| SW (Pin 7) | Switch node | Drives external inductor; connects to BST capacitor; carries high di/dt - must be routed short and away from sensitive FB/NTC traces. |
| VIN (Pin 3) | Main power input | Accepts 4.2–24V unregulated supply; requires local 10μF ceramic capacitor placed adjacent to VIN and GND pins. |
| FB (Pin 4) | Current-sense feedback | Monitors voltage across external sense resistor; regulated to 100mV - trace must be shielded from SW noise and routed near GND. |
| EN/DIM (Pin 5) | Enable and analog dimming control | DC voltage input (0.7–1.44V) sets LED current linearly; floating or >0.59V enables device - no external pull-up needed. |
| BST (Pin 2) | Bootstrap supply for high-side gate driver | Connects to SW via 0.1μF ceramic capacitor; maintains ~5.1V gate drive above SW - critical for high-side FET turn-on. |
| NTC (Pin 1) | LED temperature monitoring input | Accepts voltage from external NTC thermistor; enables ambient-temperature-dependent current foldback before thermal shutdown. |
| NC (Pin 8) | No connection | Unbonded die pad - must remain unconnected and un-routed on PCB to avoid parasitic coupling or mechanical stress. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous rectification | Integrated 80mΩ low-side switch eliminates external Schottky loss, enabling >97% efficiency at 2A output. |
| Inherent open-LED protection | No external circuitry required - device enters max-duty-cycle mode and clamps VOUT near VIN to prevent overvoltage stress. |
| Cycle-by-cycle current limiting | 5.5A typical OCP threshold protects inductor and MOSFETs during startup, short-circuit, or overload transients. |
| NTC-based thermal foldback | Linear current reduction triggered by external NTC voltage drop - extends LED lifetime without abrupt shutdown. |
| Auto-restart hiccup mode | 2.4ms fault timer forces soft-start recovery after SCP or over-temperature events - prevents latch-up in intermittent faults. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ2410GJE-AEC1-Z | Automotive-grade variant with AEC-Q100 qualification, extended -40°C to +125°C operating range, and enhanced ESD robustness (±8kV HBM). | Required for automotive cabin lighting or ADAS IR illuminators where qualification and long-term reliability are mandatory. | Select when automotive compliance, higher temperature margin, or stricter ESD immunity is required - otherwise identical functionality and pinout. |
| LT3466EDD-1#TRPBF | Non-synchronous design with external Schottky diode; lower max output current (1.2A); 1.2MHz switching; no NTC interface or analog dimming. | Suitable only for lower-current, cost-sensitive LED applications where thermal foldback and silent dimming are not needed. | Choose only if budget constraints outweigh efficiency, thermal safety, and dimming quality - requires additional diode and lacks MP2410's protection integration. |
Compared with MP2410GJE-Z, MPQ2410GJE-AEC1-Z adds automotive qualification at no layout or BOM change, while LT3466EDD-1 sacrifices efficiency, thermal intelligence, and dimming fidelity for legacy compatibility and lower unit cost.

FAQ
What is the minimum input voltage required to start MP2410GJE-Z?
The MP2410GJE-Z has a guaranteed turn-on threshold of 3.5V (typical 3.7V) with 0.12V hysteresis. Below 3.5V, the UVLO circuit holds the device in shutdown regardless of EN/DIM state. Stable operation begins at 4.2V per datasheet specifications.
Can MP2410GJE-Z drive multiple parallel LED strings?
Yes, but only with a single shared current-sense resistor at the common cathode node. Driving independent strings requires separate MP2410GJE-Z units or a multi-channel controller - the IC regulates total output current, not per-string current.
Is an external bootstrap diode required for MP2410GJE-Z?
No. The MP2410GJE-Z integrates a bootstrap charging circuit that uses the SW node to charge the BST capacitor during low-side conduction. Only a 0.1μF ceramic capacitor between BST and SW is required - no diode needed.
How does the NTC pin function without an external resistor divider?
The NTC pin sources a precise 50μA (typical) current into the external NTC thermistor. The resulting voltage drop across the NTC directly determines thermal foldback behavior - no external resistors are required for basic operation.
What happens during an LED short-circuit event?
Upon detecting overcurrent (>5.5A) or sustained high FB voltage, MP2410GJE-Z disables both MOSFETs for 2.4ms, pulls COMP low, then soft-starts again. This hiccup mode repeats until the fault clears, preventing thermal runaway or component damage.
Does MP2410GJE-Z support PWM dimming in addition to analog dimming?
No - MP2410GJE-Z implements analog dimming only via DC voltage on EN/DIM. For PWM dimming, the EN/DIM pin must be driven with a logic-level signal toggling above/below 0.59V threshold, but this causes full on/off switching, not proportional brightness control.
What is the maximum recommended PCB copper area under the exposed pad?
MPS recommends a minimum 25mm² thermal pad (5mm × 5mm) with 4–6 thermal vias (0.3mm diameter) connecting to inner ground plane. Larger copper improves θJA by up to 20°C/W, critical for sustaining 2A continuous output at elevated ambient temperatures.
