Product details
Overview
LTC7000JMSE-1#PBF from Analog Devices is a high-voltage, fast-turning high-side N-channel MOSFET gate driver IC rated for 3.5V to 135V input operation, featuring 1Ω pull-down / 2.2Ω pull-up drive strength, 35ns propagation delay, internal charge pump enabling 100% duty cycle, and overcurrent protection with adjustable trip threshold - used in industrial static switch and electronic valve control systems.
For engineers reviewing the LTC7000JMSE-1#PBF datasheet, LTC7000JMSE-1#PBF pinout, LTC7000JMSE-1#PBF application, or LTC7000JMSE-1#PBF equivalent, key selection criteria include high-side gate drive capability up to 135V VIN, thermal grade (–40°C to 150°C), absence of RUN/OVLO/ISET/IMON pins (LTC7000-1 variant), and MSOP-16 package with exposed GND pad.
Technical Context
The LTC7000JMSE-1#PBF implements a level-shifted high-side driver architecture with integrated charge pump that regulates BST–TS to 12V, enabling continuous conduction of external NMOS switches. It uses a current-sense comparator monitoring ΔVSNS across an external shunt to trigger fault shutdown after programmable timer delay.
Unlike the LTC7000 variant, the LTC7000-1 family (including LTC7000JMSE-1#PBF) omits RUN, OVLO, ISET, and IMON pins - eliminating adjustable UVLO/OVLO, current threshold programming, and current monitor output. Fault response is fixed: TGDN pulls to TS when ΔVSNS exceeds 30mV (internally clamped), with retry timing set solely by external 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 regulators. |
| Driver Output Resistance | Pull-up: 2.2Ω typ; Pull-down: 1Ω typ - enables fast switching of large gate capacitances (e.g., ≥1nF) with sub-50ns rise/fall times. |
| Propagation Delay | 35ns typ - ensures precise timing alignment between INP control signal and TGUP/TGDN transitions. |
| Charge Pump Output | Regulated 12V BST–TS - sustains 100% duty cycle gate drive for NMOS high-side switch without bootstrap diode or external capacitor recharge path. |
| Overcurrent Threshold | Fixed 30mV ΔVSNS - sets peak current limit without external resistor; minimizes sense loss while supporting low-RSENSE designs. |
| Operating Temp Range | –40°C to 150°C junction - qualified for under-hood automotive and high-temperature industrial environments. |
| Package | 16-lead MSOP with exposed GND pad - provides low θJA = 45°C/W for reliable thermal management in high-power static switch applications. |
Pinout & Package
Package: 16-lead plastic MSOP (MSE16), thermally enhanced with exposed GND pad (Pin 17) requiring PCB soldering for electrical and thermal performance. Pin pitch and creepage meet high-voltage isolation requirements per Analog Devices' MSE16(12) variant specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 2) | Main high-voltage supply input | Accepts 3.5V–135V; powers internal LDO and charge pump; requires ≥0.1µF bypass to GND. |
| VCC (Pin 3) | Internal LDO output & driver supply | Regulated ~10V output (or follows VIN if <10V); powers logic and gate drivers; decoupled with ≥1µF ceramic cap. |
| FAULT (Pin 5) | Open-drain fault indicator | Pulls low during overcurrent; typical 200Ω pull-down impedance; signals impending TGDN-to-TS transition. |
| TIMER (Pin 6) | Fault timing capacitor node | Connects to GND via CT to set warning, shutdown, and auto-retry intervals; >3.5V disables timer and forces immediate fault. |
| INP (Pin 7) | CMOS-compatible enable input | Active-high control referenced to GND; internal 1MΩ pull-down holds TGDN at TS during startup. |
| TGDN (Pin 11) | High-current gate pull-down output | Drives NMOS gate to TS (high-side source); 1Ω resistance enables rapid turn-off; connect directly to MOSFET gate. |
| TGUP (Pin 12) | High-current gate pull-up output | Drives NMOS gate to BST (bootstrapped supply); 2.2Ω resistance enables controlled turn-on; tie to TGDN for fastest edge. |
| TS (Pin 13) | High-side source reference | Connects to NMOS source terminal; serves as local ground reference for high-side sensing and driver outputs. |
| BST (Pin 14) | Bootstrapped supply rail | Swings from ~12V to (VIN + 12V); requires ≥0.1µF capacitor to TS for charge pump operation. |
| SNS+ (Pin 16) | Current sense positive input | Kelvin-connected to high-side shunt; monitors drain current via ΔVSNS; clamped comparator input with 30mV fixed threshold. |
| GND (Pin 17) | Thermal & electrical ground | Exposed pad; must be soldered to PCB copper for thermal dissipation (θJC = 10°C/W) and noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| 100% duty cycle support | Integrated charge pump maintains BST–TS at 12V regardless of VIN, enabling indefinite NMOS conduction without external bootstrap components. |
| Fast transient response | 35ns propagation delay and ≤40ns fall time allow use in high-frequency switching (>1MHz) and precision timing-critical static switch applications. |
| Short-circuit protected operation | Fixed 30mV current sense threshold triggers automatic fault shutdown and cooldown-based retry, protecting external MOSFET under sustained overload. |
| High-voltage robustness | 150V absolute max VIN and 0.657mm high-voltage pin spacing (MSE16 variant) ensure reliability in 100V+ industrial bus and battery systems. |
| Low-power shutdown mode | 1µA shutdown current (achieved when VIN < 3.5V) minimizes system standby loss in always-on power distribution modules. |

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 |
|---|---|---|---|
| LTC7000JMSE#PBF | Includes RUN, OVLO, ISET, and IMON pins; supports adjustable UVLO/OVLO, programmable current threshold (20–75mV), and ground-referenced current monitor output. | Required where dynamic current limit tuning or system-level fault reporting (via IMON) is needed; not drop-in compatible due to extra pins and different pinout. | Select LTC7000JMSE#PBF only if design requires programmable overcurrent threshold or real-time current monitoring - otherwise LTC7000JMSE-1#PBF offers simpler layout and lower BOM count. |
| TPS27081AQPWPRQ1 | Lower voltage rating (60V max), no internal charge pump (requires external bootstrap), fixed 50mV current limit, no TIMER-based retry, AEC-Q100 qualified. | Suitable for 12V–48V automotive body electronics but lacks 135V capability and autonomous fault recovery; no BST regulation for 100% duty cycle. | Choose TPS27081AQPWPRQ1 only for cost-sensitive, lower-voltage automotive applications where 100% duty cycle and high-voltage robustness are not required. |
Compared with LTC7000JMSE#PBF, LTC7000JMSE-1#PBF trades configurability for simplicity and pin count reduction; compared with TPS27081AQPWPRQ1, it delivers higher voltage operation, integrated charge pump, and autonomous fault recovery - making it uniquely suited for 100V+ industrial static switch designs.

FAQ
What is the maximum input voltage rating for the LTC7000JMSE-1#PBF?
The LTC7000JMSE-1#PBF has an absolute maximum VIN rating of 150V, with guaranteed operation from 3.5V to 135V. This allows direct interface with 48V, 60V, 96V, and 110V industrial and telecom power buses without external voltage conditioning. Exceeding 150V risks permanent damage per Absolute Maximum Ratings.
Does the LTC7000JMSE-1#PBF support 100% duty cycle operation?
Yes, the LTC7000JMSE-1#PBF supports true 100% duty cycle operation via its integrated charge pump, which regulates the BST–TS voltage to 12V independent of VIN. This eliminates reliance on external bootstrap diodes or capacitors and enables indefinite conduction of the external high-side NMOS switch.
How does overcurrent protection work on the LTC7000JMSE-1#PBF?
The LTC7000JMSE-1#PBF monitors ΔVSNS across an external sense resistor using a fixed 30mV comparator threshold. When exceeded, it asserts FAULT after a delay set by the TIMER capacitor, then pulls TGDN to TS to turn off the NMOS. After cooldown, it automatically retries - no external reset is required.
What is the operating temperature range of the LTC7000JMSE-1#PBF?
The LTC7000JMSE-1#PBF is specified for –40°C to 150°C junction temperature operation and is qualified to AEC-Q100 standards for automotive use. Its MSOP package includes an exposed GND pad that must be soldered to PCB copper to achieve the rated θJA = 45°C/W thermal performance.
Is the LTC7000JMSE-1#PBF pin-compatible with the LTC7000JMSE#PBF?
No - the LTC7000JMSE-1#PBF omits RUN, OVLO, ISET, and IMON pins present on the LTC7000JMSE#PBF, resulting in a different pin assignment and function mapping. The two variants share the same MSOP-16 package footprint but are not pin-compatible; board redesign is required for substitution.
