Product details
Overview
LTC7003IMSE#TRPBF from Analog Devices is a high-side N-channel MOSFET gate driver IC designed for protected static and switching applications up to 60V input. It integrates an internal charge pump for 100% duty cycle operation, delivers 2.2Ω pull-up / 1Ω pull-down gate drive strength, achieves 35ns propagation delay, and provides adjustable overcurrent protection with current monitor output. It is used in automotive load switch and electronic valve control systems.
For engineers reviewing the LTC7003IMSE#TRPBF datasheet, LTC7003IMSE#TRPBF pinout, LTC7003IMSE#TRPBF application, or LTC7003IMSE#TRPBF equivalent, key selection considerations include its 60V VIN capability, thermally enhanced 16-lead MSOP package with exposed GND pad, adjustable current trip threshold via ISET pin, open-drain FAULT flag, and AEC-Q100 qualification for automotive use.
Technical Context
The LTC7003IMSE#TRPBF implements a high-voltage level-shifted gate driver architecture with integrated charge pump to sustain 100% duty cycle on high-side NMOS switches. Its internal LDO generates VCC from VIN (3.5V–60V), while BST-TS voltage is regulated to ~12V for robust gate drive above TS.
Overcurrent protection uses a precision current sense comparator monitoring ΔVSNS across an external shunt, with trip threshold programmable from 20mV to 75mV via ISET. Fault response includes timer-based shutdown, automatic retry after cooldown, and open-drain FAULT assertion before TGDN pulls low.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 3.5V to 60V - supports wide-input industrial and automotive battery-fed systems without external regulators. |
| Gate Drive Strength | 2.2Ω pull-up / 1Ω pull-down - enables fast switching of large gate capacitances (e.g., >1nF) with minimal transition losses. |
| Propagation Delay | 35ns - ensures precise timing control in high-frequency or safety-critical turn-on/turn-off sequences. |
| Current Sense Threshold | 20mV to 75mV (adjustable via ISET) - allows optimization of sense resistor value and conduction loss trade-off. |
| Charge Pump Output | Regulated BST-TS ≈ 12V - sustains full gate enhancement for indefinite 100% duty cycle operation. |
| Operating Temp Range | –40°C to +125°C - qualified for under-hood automotive and harsh industrial environments. |
| Shutdown Current | 1µA - enables ultra-low-power standby in battery-sensitive applications. |
Pinout & Package
The LTC7003IMSE#TRPBF is housed in a thermally enhanced 16-lead plastic MSOP package (MSE) with exposed GND pad (Pin 17) that must be soldered to PCB for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RUN (1) | Enable control input | CMOS-compatible logic input; <0.7V disables IC (1µA shutdown), >1.21V enables full operation. |
| VIN (2) | Main supply input | Primary power source (3.5V–60V); powers internal LDO and charge pump; requires ≥0.1µF bypass to GND. |
| VCC (3) | Internal LDO output | 10V regulated supply for drivers/logic; can be overdriven externally for high-frequency apps; must not exceed VIN. |
| VCCUV (4) | VCC undervoltage lockout reference | Resistor divider sets VCC UVLO threshold (3.5V–10.5V); short to GND = 3.5V, open = 7.0V. |
| FAULT (5) | Open-drain fault indicator | Pulls low when overcurrent detected; typical 200Ω pull-down; signals impending TGDN-to-TS transition. |
| TIMER (6) | Fault timing capacitor node | CT to GND sets warning, shutdown, and retry intervals; >3.5V enables immediate fast-turn-off mode. |
| INP (7) | CMOS input signal | Ground-referenced logic input with 1MΩ internal pull-down; controls TGUP/TGDN state; VIH=2.0V, VIL=1.6V. |
| OVLO (8) | Input overvoltage lockout | Resistor divider sets VIN OVLO threshold; >1.21V forces TGDN-to-TS and triggers fault sequence. |
| ISET (9) | Current trip threshold adjust | Resistor to GND programs ΔVTH from 20mV to 75mV (ΔVSNS = VSNS+ – VSNS–); open = 30mV default. |
| IMON (10) | Current monitor output | Analog voltage = 20×ΔVSNS (0–1.5V range); referenced to GND; 100kΩ output impedance. |
| TGDN (11) | High-current gate pull-down | Drives external MOSFET gate to TS; 1Ω RDS(ON); direct connection minimizes turn-off time. |
| TGUP (12) | High-current gate pull-up | Drives external MOSFET gate to BST; 2.2Ω RDS(ON); tie to TGDN for fastest transitions. |
| TS (13) | Top-source reference | High-side source connection point; also serves as GND reference in ground-referenced configurations. |
| BST (14) | Bootstrap supply | Output of internal charge pump; requires ≥0.1µF capacitor to TS; swing = 12V to (VIN + 12V). |
| SNS– (15) | Current sense negative | Low-side connection of external sense resistor; Kelvin-connected via ≥100Ω resistor for noise immunity. |
| SNS+ (16) | Current sense positive | High-side connection of external sense resistor; Kelvin-connected directly to shunt for accuracy. |
| GND (17) | Power/thermal ground | Exposed pad; must be soldered to PCB plane for thermal dissipation (θJA = 45°C/W) and electrical stability. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side NMOS gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5060MMX/NOPB | Lower VIN max (65V vs 60V), no internal charge pump (requires external bootstrap), fixed 50mV current threshold. | Lacks 100% duty cycle support and adjustable trip; suited for simpler, cost-sensitive overvoltage/overcurrent protection only. | Select when bootstrap complexity is acceptable and duty cycle <100%; avoid where sustained conduction is required. |
| TPS2HB35-Q1 | Integrated 35mΩ high-side FET, 40V max VIN, built-in diagnostics (open-load, short-to-battery), no IMON output. | Monolithic smart switch vs driver-only; lacks current monitor and external MOSFET flexibility. | Select for space-constrained automotive modules needing integrated FET and ASIL-B compliance; not a drop-in replacement. |

FAQ
What is the maximum input voltage rating for the LTC7003IMSE#TRPBF?
The LTC7003IMSE#TRPBF has an absolute maximum VIN rating of 65V, with guaranteed operation from 3.5V to 60V. Exceeding 65V may cause permanent damage. The device is optimized for 12V, 24V, and 48V automotive and industrial bus systems, and its internal protection circuitry actively disables the gate driver if VIN falls below 3.5V or exceeds safe thresholds set via OVLO.
How does the LTC7003IMSE#TRPBF achieve 100% duty cycle operation?
The LTC7003IMSE#TRPBF achieves 100% duty cycle using an integrated charge pump that regulates the BST–TS voltage to approximately 12V, independent of output duty cycle. This ensures the gate of the external high-side NMOS remains fully enhanced even during continuous conduction, eliminating the need for external bootstrap diodes or capacitors typically required in self-biased gate drivers.
Can the current trip threshold of the LTC7003IMSE#TRPBF be adjusted, and how?
Yes, the current trip threshold (ΔVTH) of the LTC7003IMSE#TRPBF is adjustable from 20mV to 75mV via the ISET pin. Connecting a resistor from ISET to GND sets the threshold as VISET/20; leaving ISET open defaults to 30mV. The internal clamp ensures ΔVTH stays within 20–75mV regardless of external resistor choice, enabling precise optimization of sense resistor value and conduction loss.
What is the purpose of the IMON pin on the LTC7003IMSE#TRPBF?
The IMON pin on the LTC7003IMSE#TRPBF provides a ground-referenced analog voltage output equal to 20× the voltage across the external sense resistor (ΔVSNS), ranging from 0V to 1.5V. It enables real-time current monitoring without external amplification, supporting closed-loop control, diagnostics, and system telemetry in applications like motor drives and power supplies.
Is the LTC7003IMSE#TRPBF qualified for automotive applications?
Yes, the LTC7003IMSE#TRPBF is AEC-Q100 qualified for automotive applications (Grade I, –40°C to +125°C). It undergoes rigorous stress testing including temperature cycling, humidity bias, and ESD qualification, and is manufactured under controlled automotive processes. The part marking "I" in LTC7003IMSE#TRPBF explicitly denotes its automotive-grade qualification and extended temperature guarantee.
