Product details
Overview
LTC7003IMSE#PBF from Analog Devices is a high-side N-channel MOSFET gate driver IC designed for protected static and high-frequency 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 load switches and industrial high-voltage power control systems.
For engineers reviewing the LTC7003IMSE#PBF datasheet, LTC7003IMSE#PBF pinout, LTC7003IMSE#PBF application, or LTC7003IMSE#PBF equivalent, key selection considerations include its 60V VIN capability, programmable current trip threshold (20–75mV), open-drain FAULT flag, thermally enhanced 16-lead MSOP package, and AEC-Q100 qualification for automotive use.
Technical Context
The LTC7003IMSE#PBF implements a level-shifted high-side driver architecture with integrated charge pump that regulates BST–TS to 12V, enabling indefinite conduction of external N-MOSFETs. Its current sense comparator monitors ΔVSNS across an external shunt resistor and triggers fault shutdown after a user-set timer delay.
It supports fast turn-on/turn-off via dual gate drivers (TGUP/TGDN) with 35ns propagation delay and sub-13ns rise/fall times into 1nF loads. Protection logic includes adjustable VIN undervoltage/overvoltage lockouts (via RUN/OVLO pins), VCC UVLO (via VCCUV), BST–TS floating UVLO (3.1V), and thermal shutdown at ~180°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 3.5V to 60V - supports wide-input industrial and automotive battery systems without external regulators. |
| Gate Drive Strength | 2.2Ω pull-up / 1Ω pull-down - enables fast switching of large gate capacitances with minimal Miller plateau time. |
| Propagation Delay | 35ns - ensures precise timing control in high-frequency synchronous or PWM-based power paths. |
| Current Sense Threshold | 20mV to 75mV (adjustable via ISET) - allows low-loss sensing with sub-10mΩ shunts while maintaining accuracy. |
| Charge Pump Output | Regulated 12V BST–TS - sustains 100% duty cycle operation without external bootstrap diode or capacitor degradation. |
| Fault Response | Open-drain FAULT pin + automatic retry after cooldown - provides system-level fault signaling and self-recovery without host intervention. |
| Package | 16-lead MSOP with exposed GND pad - delivers θJC = 10°C/W thermal resistance for high-power density designs. |
Pinout & Package
Package: 16-lead plastic MSOP (MSE) with exposed thermal pad (Pin 17 = GND). Requires soldering of exposed pad to PCB for rated thermal and electrical performance (θJA = 45°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RUN (1) | Enable/Shutdown Control | CMOS-compatible input; >1.21V enables operation, <0.7V reduces supply current to 1µA. |
| VIN (2) | Main Input Supply | Primary power source (3.5–60V); requires ≥0.1µF bypass to GND. |
| VCC (3) | Internal LDO Output | 10V regulated output for gate drivers; can be overdriven externally for high-frequency apps. |
| VCCUV (4) | VCC Undervoltage Lockout Set | Resistor-to-GND sets VCC UVLO threshold (3.5V–10.5V) via 7× scaling. |
| FAULT (5) | Fault Indicator Output | Open-drain signal pulled low during overcurrent; typical 200Ω pull-down impedance. |
| TIMER (6) | Fault Timing Capacitor Node | Connects to GND via CT to set warning, shutdown, and auto-retry intervals. |
| INP (7) | Logic Input Signal | CMOS-compatible gate control (VIH=2.0V, VIL=1.6V); internal 1MΩ pull-down. |
| OVLO (8) | Input Overvoltage Lockout | Resistive divider sets VIN OVLO threshold; >1.21V forces TGDN to TS. |
| ISET (9) | Current Trip Threshold Set | Resistor-to-GND programs ΔVTH from 20mV (min) to 75mV (max). |
| IMON (10) | Current Monitor Output | Ground-referenced voltage = 20×ΔVSNS (0–1.5V range); 100kΩ output impedance. |
| TGDN (11) | High-Side Gate Pull-Down | Drives external MOSFET gate to TS; optimized for fast turn-off with low RDS(ON). |
| TGUP (12) | High-Side Gate Pull-Up | Drives gate to BST; tied to TGDN for max speed or series-resistor controlled slew rate. |
| TS (13) | Top-Side Source Reference | High-side source node (up to 60V above GND); also serves as return for SNS–. |
| BST (14) | Bootstrap Supply | Charge pump output; requires ≥0.1µF capacitor to TS; swing = 12V to (VIN+12V). |
| SNS– (15) | Current Sense Negative Input | Kelvin-connected to shunt resistor; must use ≥100Ω series resistor for noise immunity. |
| SNS+ (16) | Current Sense Positive Input | Kelvin-connected to shunt resistor; referenced to TS; defines ΔVSNS for overcurrent detection. |
| GND (17) | Thermal & Electrical Ground | Exposed pad; must be soldered to PCB plane for thermal dissipation and signal integrity. |
Key Features
| Feature | Design Value |
|---|---|
| 100% Duty Cycle Support | Integrated charge pump maintains BST–TS at 12V regardless of VIN or duty cycle - eliminates need for external bootstrap diode. |
| Adjustable Overcurrent Protection | ISET pin allows precise setting of current trip threshold (20–75mV) to match MOSFET RDS(ON) and system loss budget. |
| Fast Turn-On/Turn-Off | 35ns propagation delay + 13ns rise/fall into 1nF load enables high-frequency (>1MHz) switching or rapid static switching response. |
| Automotive-Qualified Operation | AEC-Q100 Grade I (–40°C to +125°C junction) - validated for under-hood and battery-management applications. |
| Comprehensive Voltage Monitoring | Independent lockouts for VIN (RUN/OVLO), VCC (VCCUV), and BST–TS (floating UVLO) prevent operation outside safe operating area. |

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), no internal charge pump (requires external bootstrap), fixed 50mV current threshold, no IMON output. | Best suited for cost-sensitive 12V/24V industrial switches where 100% duty cycle is not required. | Select when bootstrap complexity is acceptable and current monitoring is unnecessary. |

FAQ
What is the maximum input voltage supported by the LTC7003IMSE#PBF?
The LTC7003IMSE#PBF supports a continuous input voltage range of 3.5V to 60V on the VIN pin, with absolute maximum rating of 65V. This enables direct interface with 12V, 24V, 48V, and 60V battery or bus systems without external regulation. The device also tolerates transient overvoltages up to 65V on TS, SNS+, and SNS– pins, ensuring robustness in noisy high-voltage environments.
Does the LTC7003IMSE#PBF require an external bootstrap diode?
No, the LTC7003IMSE#PBF does not require an external bootstrap diode. It contains an integrated charge pump that generates and regulates the BST–TS voltage to 12V, enabling reliable 100% duty cycle operation of external high-side N-MOSFETs. An external 0.1µF capacitor between BST and TS is required, but no diode is needed - simplifying layout and improving reliability.
How is overcurrent protection configured on the LTC7003IMSE#PBF?
Overcurrent protection on the LTC7003IMSE#PBF is configured using the ISET pin: connecting a resistor from ISET to GND sets the current sense threshold ΔVTH from 20mV to 75mV (ΔVTH = VISET / 20). With ISET open, ΔVTH defaults to 30mV. The actual trip point is ΔVSNS = (VSNS+ – VSNS–), and fault response timing is set by a capacitor from TIMER to GND.
Is the LTC7003IMSE#PBF qualified for automotive applications?
Yes, the LTC7003IMSE#PBF is AEC-Q100 qualified for automotive applications (Grade I, –40°C to +125°C junction temperature). It is manufactured with controlled processes and tested to meet automotive reliability standards, including HTOL, TC, and ESD requirements. The part marking "IMSE" and #PBF suffix confirm its automotive-grade qualification and lead-free finish.
What is the purpose of the IMON pin on the LTC7003IMSE#PBF?
The IMON pin on the LTC7003IMSE#PBF provides a ground-referenced analog output voltage equal to 20× the voltage across the external sense resistor (ΔVSNS), ranging from 0V to 1.5V. It enables real-time current monitoring without additional amplification, supporting diagnostics, closed-loop control, or system health reporting. IMON is active only when TGUP is high and has 100kΩ output impedance with internal 100kΩ pull-down when INP is low.
