Product details
Overview
LTC7000IMSE-1#WTRPBF from Analog Devices is a high-voltage, fast-turn-on high-side N-channel MOSFET gate driver IC operating from 3.5V to 135V input, featuring 35ns propagation delay, 1Ω pull-down / 2.2Ω pull-up gate drive strength, internal charge pump for 100% duty cycle operation, and overcurrent protection with adjustable trip threshold - used in industrial load switching and electronic valve control.
For engineers reviewing the LTC7000IMSE-1#WTRPBF datasheet, LTC7000IMSE-1#WTRPBF pinout, LTC7000IMSE-1#WTRPBF application, or LTC7000IMSE-1#WTRPBF equivalent, key selection criteria include VIN range (3.5–135V), BST-TS voltage capability (up to 14V), fault timing via external capacitor, thermal grade (–40°C to 125°C), and absence of RUN/OVLO/ISET/IMON pins versus LTC7000 variants.
Technical Context
The LTC7000IMSE-1#WTRPBF implements a level-shifted high-side driver architecture with integrated charge pump that sustains BST-TS at 12V for full enhancement of external NMOS switches, enabling indefinite conduction without external bootstrap diode or capacitor recharging constraints. It uses a current-sense comparator monitoring ΔVSNS across an external shunt to trigger fault shutdown after programmable timer delay.
Unlike the LTC7000, the LTC7000-1 variant omits RUN, OVLO, ISET, and IMON pins - eliminating user-adjustable undervoltage/overvoltage lockouts and current trip programming, resulting in fixed 30mV current sense threshold and simplified interface. Fault signaling remains via open-drain FAULT pin, and automatic retry is retained with cooldown period governed by TIMER capacitor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 3.5V to 135V - supports wide-input industrial and automotive supply rails without external regulation. |
| Propagation Delay | 35ns - enables 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 gate charging/discharging. |
| BST-TS Output Voltage | 12V typical (up to 14V) - ensures full gate enhancement of high-voltage NMOS devices at 100% duty cycle. |
| Current Sense Threshold | 30mV fixed (ΔVTH) - sets overcurrent trip point without external resistor; optimized for low-loss sensing. |
| Operating Temperature | –40°C to 125°C - qualified for extended industrial environments with guaranteed performance across full range. |
| Shutdown Current | 1µA - ultra-low quiescent draw during inactive state, critical for battery-backed or always-on systems. |
Pinout & Package
Package: 16-lead plastic MSOP (MSE16) with exposed GND pad (Pin 17), thermally enhanced for high-power dissipation; creepage-optimized layout for 135V operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 2) | Main high-voltage supply input | Accepts 3.5–135V; powers internal LDO and charge pump; requires ≥0.1µF bypass to GND. |
| VCC (Pin 3) | Internal LDO output & gate driver supply | Regulated ~10V output; decoupled with ≥1µF ceramic cap; can be overdriven externally for high-frequency use. |
| FAULT (Pin 5) | Open-drain fault indicator | Pulls low when overcurrent detected; 200Ω typical pull-down impedance; signals impending TGDN activation. |
| TIMER (Pin 6) | Fault timing capacitor node | Connects to GND via CT to set warning, shutdown, and auto-retry intervals; >3.5V disables timer. |
| INP (Pin 7) | CMOS-compatible enable input | Active-high logic input referenced to GND; internal 1MΩ pull-down holds TGDN low at startup. |
| TGDN (Pin 11) | High-current gate pull-down output | Drives external MOSFET gate to TS (high-side source); direct connection minimizes turn-off delay. |
| TGUP (Pin 12) | High-current gate pull-up output | Drives gate to BST; tied to TGDN for fastest transitions; series resistor controls dV/dt during turn-on. |
| TS (Pin 13) | High-side source reference | Connects to MOSFET source; serves as local ground reference for high-side driver stage. |
| BST (Pin 14) | Bootstrap supply output | Provides floating 12V gate drive voltage relative to TS; requires ≥0.1µF capacitor to TS. |
| SNS+ (Pin 16) | Current sense positive input | Kelvin-connected to high-side shunt; monitors drain current via ΔVSNS = VSNS+ – VSNS–. |
| SNS– (Pin 15) | Current sense negative input | Connected to shunt via ≥100Ω resistor; completes current sense path with SNS+. |
| GND (Pin 17) | Thermal & electrical ground | Exposed pad must be soldered to PCB for thermal management and optimal EMI performance. |
Key Features
| Feature | Design Value |
|---|---|
| 100% duty cycle support | Integrated charge pump maintains BST-TS at 12V regardless of VIN, enabling continuous conduction without gate drive collapse. |
| Fast 35ns propagation delay | Minimizes timing uncertainty between INP edge and TGUP/TGDN transition - critical for synchronous or time-critical switching. |
| Short-circuit protected operation | Current sense comparator triggers fault within 70ns of overcurrent step; TGDN pulled to TS to disable MOSFET before damage occurs. |
| Automated fault recovery | After fault timeout and cooldown, device automatically retries - eliminates need for external reset circuitry in self-healing systems. |
| High-voltage capable MSOP package | MSE16 footprint with 0.157mm pin spacing meets IPC-2221 creepage requirements for 135V operation in compact layouts. |

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 |
|---|---|---|---|
| LTC7000IMSE#WTRPBF | Includes RUN, OVLO, ISET, IMON pins; adjustable current trip (20–75mV), programmable UVLO/OVLO. | Required where dynamic current limit tuning or supply rail monitoring is needed; adds complexity and BOM count. | Select when design requires configurable protection thresholds or diagnostic feedback via IMON. |
| LM5109BMAX/NOPB | 100V max VIN, no integrated charge pump, requires external bootstrap diode/capacitor, no overcurrent protection. | Suitable only for lower-voltage, non-fault-tolerant applications; lacks current sensing and auto-retry. | Choose for cost-sensitive, <100V designs without protection requirements and where board space allows external bootstrap components. |
Compared with LTC7000IMSE#WTRPBF, the LTC7000IMSE-1#WTRPBF trades configurability for simplicity and reduced external component count, while LM5109BMAX/NOPB offers lower voltage capability without integrated protection - making LTC7000IMSE-1#WTRPBF optimal for fixed-threshold, high-reliability 135V static switching.

FAQ
What is the maximum input voltage rating for the LTC7000IMSE-1#WTRPBF?
The LTC7000IMSE-1#WTRPBF has an absolute maximum VIN rating of 150V, with guaranteed operation up to 135V. This allows safe use in 100V DC industrial buses and 48V/60V automotive systems with margin. Exceeding 135V during normal operation risks violating the specified operating range, though the device withstands transient spikes per its absolute maximum ratings.
Does the LTC7000IMSE-1#WTRPBF support 100% duty cycle operation?
Yes, the LTC7000IMSE-1#WTRPBF supports true 100% duty cycle operation via its internal charge pump, which maintains BST-TS at ~12V independent of VIN or switching frequency. This eliminates reliance on external bootstrap diodes or capacitors that would otherwise discharge during prolonged on-states - a key advantage over conventional high-side drivers.
How does overcurrent protection work in the LTC7000IMSE-1#WTRPBF?
The LTC7000IMSE-1#WTRPBF monitors ΔVSNS across an external sense resistor using an internal comparator with a fixed 30mV threshold. When exceeded, it asserts FAULT after a delay set by the TIMER capacitor, then pulls TGDN to TS to disable the MOSFET. After cooldown, it automatically retries - all without external intervention.
What is the purpose of the TS pin on the LTC7000IMSE-1#WTRPBF?
The TS (Top Source) pin on the LTC7000IMSE-1#WTRPBF serves as the local ground reference for the high-side driver stage and connects directly to the source terminal of the external NMOS switch. It enables level-shifting circuitry to drive the gate relative to the floating source, allowing proper enhancement of high-side configurations where the source is not at system ground.
Is the LTC7000IMSE-1#WTRPBF AEC-Q100 qualified?
Yes, the LTC7000IMSE-1#WTRPBF carries AEC-Q100 qualification for automotive applications, with guaranteed operation from –40°C to 125°C junction temperature. The "W" suffix in the part number denotes automotive-grade manufacturing control, including enhanced reliability testing and traceability - confirmed in Analog Devices' official automotive product documentation.
