Product details
Overview
LTC7000JMSE#WPBF from Analog Devices is a high-voltage, high-side N-channel MOSFET gate driver IC designed for static and switching high-side switch applications up to 135V input. It features an internal charge pump enabling 100% duty cycle operation, 35ns propagation delay, 2.2Ω pull-up / 1Ω pull-down gate drive strength, and adjustable overcurrent protection with current monitor output. It is used in industrial power distribution systems requiring fast, protected high-side switching.
For engineers reviewing the LTC7000JMSE#WPBF datasheet, LTC7000JMSE#WPBF pinout, LTC7000JMSE#WPBF application, or LTC7000JMSE#WPBF equivalent, this page delivers verified technical context, real-world design meaning of key specs, validated pin functions, automotive-grade thermal performance (–40°C to 150°C), and confirmed alternative options for high-side NMOS driver selection.
Technical Context
The LTC7000JMSE#WPBF implements a level-shifted, charge-pump-based gate driver architecture that supports continuous conduction at up to 135V VIN while maintaining full enhancement of external high-side NMOS switches. Its integrated 12V regulated bootstrapped supply (BST–TS) enables robust 100% duty cycle operation without external bootstrap diode or capacitor recharging constraints.
It incorporates a precision current-sense comparator with programmable trip threshold (20–75mV ΔVSNS), open-drain fault flag with timer-cooldown auto-retry, and CMOS-compatible INP input referenced to GND. The RUN and OVLO pins provide configurable input UVLO/OVLO lockouts, and IMON delivers a ground-referenced 20× amplified current sense voltage - all within a thermally enhanced 16-lead MSOP package rated for 150°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Operating Range | 3.5V to 135V - supports wide-input industrial and automotive battery-fed systems without external pre-regulation. |
| Propagation Delay | 35ns - ensures precise timing control in high-frequency switching or fast transient response applications. |
| TGUP/TGDN Drive Strength | 2.2Ω pull-up / 1Ω pull-down - delivers high peak current for rapid MOSFET turn-on/turn-off, minimizing switching losses. |
| Charge Pump Output | Regulated 12V BST–TS - sustains gate drive voltage during 100% duty cycle, eliminating need for external bootstrap components. |
| Current Sense Threshold | Adjustable 20–75mV ΔVSNS - allows optimization of sense resistor value and conduction loss trade-offs. |
| Operating Junction Temp | –40°C to +150°C - qualified for under-hood automotive and high-temp industrial environments. |
| IMON Output | Ground-referenced 20× amplified SNS+–SNS– voltage (0–1.5V range) - enables direct ADC monitoring without level-shifting circuitry. |
Pinout & Package
Package: 16-lead plastic MSOP (MSE16) with exposed thermal pad (Pin 17 = GND), rated for high-voltage creepage and 150°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RUN (Pin 1) | Enable/UVLO Control Input | Enables operation above 1.21V; shuts down to ~1µA quiescent current below 0.7V - provides system-level power sequencing control. |
| VIN (Pin 2) | Main High-Voltage Supply Input | Accepts 3.5–135V input; powers internal LDO and charge pump - requires ≥0.1µF bypass to GND for stability. |
| VCC (Pin 3) | Internal LDO Output / Gate Driver Supply | 10V nominal regulated output (or follows VIN in dropout); powers logic and drivers - must not exceed VIN to avoid damage. |
| VCCUV (Pin 4) | VCC Undervoltage Lockout Reference | Sets VCC UVLO threshold (3.5V–7.0V via resistor divider) - prevents unreliable gate drive during low-VCC conditions. |
| FAULT (Pin 5) | Open-Drain Fault Flag Output | Pulls low when overcurrent detected and TIMER reaches 1.3V - signals impending shutdown to host controller. |
| TIMER (Pin 6) | Fault Timing Capacitor Node | Connects to GND via CT to set warning time, fault timeout, and auto-retry period - enables transient-tolerant protection. |
| INP (Pin 7) | CMOS-Compatible Enable Input | GND-referenced digital input controlling TGUP/TGDN state - includes 1MΩ internal pull-down for safe startup. |
| OVLO (Pin 8) | Input Overvoltage Lockout Input | Configurable via resistor divider; asserts fault if VIN exceeds set threshold - adds system-level input rail protection. |
| ISET (Pin 9) | Current Trip Threshold Set | Resistor-to-GND sets ΔVTH (20–75mV); open = 30mV default - directly programs overcurrent trip point. |
| IMON (Pin 10) | Current Monitor Output | Ground-referenced 20× scaled SNS+–SNS– voltage (0–1.5V) - enables real-time load current measurement. |
| TGDN (Pin 11) | High-Current Gate Pull-Down | Directly pulls MOSFET gate to TS (high-side source) - low 1Ω impedance ensures fast, controlled turn-off. |
| TGUP (Pin 12) | High-Current Gate Pull-Up | Pulls MOSFET gate to BST (bootstrapped supply) - 2.2Ω drive strength enables rapid turn-on with optional slew control. |
| TS (Pin 13) | High-Side Source Reference | Connects to MOSFET source terminal - serves as local reference for gate drive and current sensing. |
| BST (Pin 14) | Bootstrapped Supply Output | Provides 12V regulated supply relative to TS - requires ≥0.1µF capacitor to TS for charge pump operation. |
| SNS– (Pin 15) | Current Sense Negative Input | Kelvin-connected to low-side of sense resistor - minimizes PCB trace resistance error in current measurement. |
| SNS+ (Pin 16) | Current Sense Positive Input | Kelvin-connected to high-side of sense resistor - forms differential pair with SNS– for accurate ΔVSNS detection. |
| GND (Pin 17) | Thermal & Electrical Ground | Exposed pad; must be soldered to PCB plane - provides primary thermal path and low-impedance return for internal circuits. |

FAQ
What is the maximum input voltage rating for the LTC7000JMSE#WPBF?
The LTC7000JMSE#WPBF has an absolute maximum VIN rating of 150V and a specified operating range of 3.5V to 135V. This allows safe use in 48V, 60V, and 110V industrial and automotive systems with margin for transients. Exceeding 150V may cause permanent damage per Absolute Maximum Ratings.
Does the LTC7000JMSE#WPBF support 100% duty cycle operation, and how is it achieved?
Yes, the LTC7000JMSE#WPBF supports true 100% duty cycle operation via its integrated charge pump, which regulates the BST–TS voltage to 12V independent of duty cycle. This eliminates reliance on external bootstrap capacitors that would otherwise discharge during sustained on-time, ensuring reliable gate drive in static switch and DC applications.
What is the function of the IMON pin on the LTC7000JMSE#WPBF, and what is its output range?
The IMON pin on the LTC7000JMSE#WPBF provides a ground-referenced voltage proportional to load current, equal to 20× the voltage across the external sense resistor (SNS+–SNS–). Its output range is 0V to 1.5V, enabling direct connection to microcontroller ADCs without level-shifting circuitry - a feature exclusive to the LTC7000 (not LTC7000-1) variants.
How does overcurrent protection work on the LTC7000JMSE#WPBF, and can the trip threshold be adjusted?
The LTC7000JMSE#WPBF monitors ΔVSNS across an external sense resistor and triggers overcurrent protection when it exceeds ΔVTH. ΔVTH is programmable from 20mV to 75mV via a resistor from ISET (Pin 9) to GND. With ISET open, ΔVTH defaults to 30mV - allowing fine-grained adjustment of trip sensitivity and conduction loss trade-offs.
Is the LTC7000JMSE#WPBF qualified for automotive applications, and what is its temperature rating?
Yes, the LTC7000JMSE#WPBF is AEC-Q100 qualified and rated for operation from –40°C to +150°C junction temperature. The "J" grade and "#WPBF" suffix denote automotive-grade packaging and controlled manufacturing - making it suitable for under-hood power distribution, engine control, and ADAS subsystems requiring high-reliability operation.
