Product details
Overview
LTC7003EMSE#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, and features adjustable overcurrent protection with 35ns propagation delay. It is used in automotive electronic valve control and industrial load switching where fast, fault-protected high-side switching is required.
For engineers reviewing the LTC7003EMSE#TRPBF datasheet, LTC7003EMSE#TRPBF pinout, LTC7003EMSE#TRPBF application, or LTC7003EMSE#TRPBF equivalent, key selection criteria include its 60V VIN rating, programmable current trip threshold (20–75mV), open-drain FAULT flag, thermally enhanced MSOP-16 package with exposed pad, and AEC-Q100 qualification for automotive-grade reliability.
Technical Context
The LTC7003EMSE#TRPBF implements a high-voltage level-shifted output stage with integrated charge pump to sustain gate drive above TS (up to 60V) without external bootstrap diodes. Its internal comparator monitors ΔVSNS across an external sense resistor and triggers fault shutdown after a capacitor-set timeout, followed by automatic retry after cooldown.
It supports dual-mode protection: standard timed fault response via TIMER pin capacitor and fast-turn-off mode when TIMER is tied to VCC. The IMON pin provides a ground-referenced 20× amplified current sense voltage (0–1.5V), while RUN, OVLO, and VCCUV pins enable configurable undervoltage/overvoltage lockouts with hysteresis.
Key Specifications

Pinout & Package
Package: 16-lead plastic MSOP with exposed thermal pad (Pin 17 = GND), θJA = 45°C/W, θJC = 10°C/W. Exposed pad must be soldered to PCB for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RUN (1) | Enable/Shutdown Control | CMOS-compatible input; >1.21V enables operation, <0.7V shuts down to 1µA quiescent current. |
| VIN (2) | Main Supply Input | Primary power source (3.5–60V); requires ≥0.1µF bypass to GND. |
| VCC (3) | Internal LDO Output | 10V regulated supply for logic and drivers; can be overdriven externally for high-frequency use. |
| VCCUV (4) | VCC Undervoltage Lockout Set | Resistor-to-GND sets VCC UVLO threshold (3.5V–10.5V) via 7× scaling. |
| FAULT (5) | Open-Drain Fault Flag | Pulls low during overcurrent; typical 200Ω pull-down impedance; indicates imminent TGDN activation. |
| TIMER (6) | Fault Timing Capacitor Node | Connects to GND via CT to set warning, shutdown, and retry intervals; >3.5V enables fast-turn-off mode. |
| INP (7) | Logic Input Signal | CMOS-compatible gate control (VIH=2.0V, VIL=1.6V); internal 1MΩ pull-down holds TGDN low at startup. |
| OVLO (8) | Input Overvoltage Lockout | Resistor divider sets OVLO threshold (1.11V–1.26V); pulls TGDN to TS when exceeded. |
| ISET (9) | Current Trip Threshold Set | Resistor-to-GND programs ΔVTH from 20mV to 75mV (clamped min/max); open = 30mV default. |
| IMON (10) | Current Monitor Output | Ground-referenced 20× amplified SNS+–SNS– voltage (0–1.5V); 100kΩ output impedance. |
| TGDN (11) | High-Side Gate Pull-Down | Direct connection to MOSFET gate ensures fastest turn-off; sinks current to TS (not GND). |
| TGUP (12) | High-Side Gate Pull-Up | Drives gate toward BST; tie to TGDN for max speed or add series resistor for slew control. |
| TS (13) | Top-Side Source Reference | High-side return node (0–60V relative to GND); connects to MOSFET source and BST capacitor. |
| BST (14) | Bootstrap Supply | Charged to ~12V above TS via internal charge pump; requires ≥0.1µF capacitor to TS. |
| SNS– (15) | Current Sense Negative | Low-side connection of sense resistor; Kelvin-connected via ≥100Ω resistor for noise immunity. |
| SNS+ (16) | Current Sense Positive | High-side connection of sense resistor; Kelvin-connected directly for accurate ΔVSNS measurement. |
| GND (17) | Thermal & Electrical Ground | Exposed pad; must be soldered to PCB plane for thermal dissipation and signal reference integrity. |

FAQ
What is the maximum input voltage rating for the LTC7003EMSE#TRPBF?
The LTC7003EMSE#TRPBF supports a maximum input voltage (VIN) of 60V, with absolute maximum ratings extending to 65V. This enables direct interface with 48V industrial buses and 12V/24V automotive systems including cold-crank transients. Operation above 60V violates recommended conditions and risks permanent damage.
How does the LTC7003EMSE#TRPBF achieve 100% duty cycle operation?
The LTC7003EMSE#TRPBF achieves 100% duty cycle operation through an integrated charge pump that regulates the BST–TS voltage to approximately 12V, independent of TS voltage (0–60V). This ensures continuous gate enhancement of the external high-side NMOS, eliminating bootstrap diode limitations and enabling indefinite on-time without gate voltage droop.
Can the LTC7003EMSE#TRPBF drive a MOSFET with gate charge higher than 1nF?
Yes, the LTC7003EMSE#TRPBF can drive MOSFETs with gate capacitance exceeding 1nF. Its 2.2Ω pull-up and 1Ω pull-down resistances deliver strong peak current, and typical rise/fall times remain below 90ns even into 10nF loads. For very large Qg devices, adding a small series resistor on TGUP/TGDN helps manage EMI and dV/dt without compromising functionality.
What is the function of the IMON pin on the LTC7003EMSE#TRPBF?
The IMON pin on the LTC7003EMSE#TRPBF provides a ground-referenced analog voltage output equal to 20× the voltage across the external sense resistor (SNS+–SNS–), ranging from 0V to 1.5V. It enables real-time current monitoring without isolated amplifiers, supports closed-loop current limiting, and simplifies diagnostic logging in automotive and industrial systems.
Is the LTC7003EMSE#TRPBF qualified for automotive applications?
Yes, the LTC7003EMSE#TRPBF is AEC-Q100 qualified for automotive applications (Grade I, –40°C to +125°C junction temperature). It undergoes stress testing per AEC-Q100 Rev H, including HTOL, TC, UHAST, and ESD, and is manufactured in certified automotive production lines-making it suitable for engine control, body electronics, and ADAS power stages.
