Product details
Overview
LTC7000EMSE-1#TRPBF from Analog Devices is a high-voltage, fast-turning high-side N-channel MOSFET gate driver IC operating from 3.5V to 135V input supply, featuring 35ns propagation delay, 1Ω pull-down / 2.2Ω pull-up gate drive strength, internal charge pump for 100% duty cycle operation, and adjustable overcurrent protection - used in industrial static switch and electronic valve control systems.
For engineers reviewing the LTC7000EMSE-1#TRPBF datasheet, LTC7000EMSE-1#TRPBF pinout, LTC7000EMSE-1#TRPBF application, or LTC7000EMSE-1#TRPBF equivalent, this page delivers verified electrical specs, thermal package details, functional pin roles, real-world use cases, and validated alternative parts for high-side switching designs requiring robust fault handling and fast transient response.
Technical Context
The LTC7000EMSE-1#TRPBF implements a level-shifted CMOS-compatible input stage driving high-side NMOS switches with bootstrapped gate voltage (BST–TS up to 14V), using an internal charge pump that sustains 100% duty cycle without external components. It integrates a current-sense comparator monitoring ΔVSNS across an external shunt resistor, with fixed 30mV trip threshold (ISET open) and automatic retry timing controlled by an external capacitor on the TIMER pin.
Unlike the LTC7000 variant, the LTC7000-1 family omits RUN, OVLO, ISET, and IMON pins - simplifying configuration but removing programmable UVLO/OVLO, adjustable current limit, and current monitor output. Its fault flag (FAULT) is open-drain, asserted after timer-based overcurrent detection, and it supports thermal shutdown at ~180°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 3.5V to 135V - enables direct interface with wide-input industrial power rails up to 135V DC without external regulators. |
| Propagation Delay | 35ns - ensures precise timing alignment between INP logic edge and TGUP/TGDN state change for high-frequency switching. |
| Gate Drive Strength | 1Ω pull-down / 2.2Ω pull-up - delivers fast turn-off and controlled turn-on slew rate into large gate capacitances (e.g., 1nF load). |
| Current Sense Threshold | 30mV (fixed, ISET open) - sets overcurrent trip point for low-loss sensing with ≤0.007Ω shunt resistors at 3A continuous. |
| Operating Temp Range | –40°C to +125°C - qualified for industrial environments with guaranteed performance across full junction temperature range. |
| Package | 16-lead MSOP (MSE16), exposed pad soldered to GND - provides 45°C/W θJA thermal resistance and high-voltage creepage spacing (0.157mm). |
| Fault Response | Timer-based auto-retry with cooldown period - isolates short-circuit faults while allowing recovery without manual reset. |
Pinout & Package
Package: 16-lead plastic MSOP (MSE16), thermally enhanced with exposed GND pad (Pin 17). High-voltage pin spacing is 0.157mm per Analog Devices specification for 135V operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RUN | Not present on LTC7000-1 | Omitted - device powers up automatically when VIN ≥ 3.5V; no external enable control. |
| VIN | Main high-voltage supply input | Accepts 3.5V–135V; powers internal LDO and charge pump; requires ≥0.1µF bypass to GND. |
| VCC | Internal LDO output (10V nominal) | Supplies gate drivers and logic; can be overdriven externally for high-frequency applications; must not exceed VIN. |
| VCCUV | Not present on LTC7000-1 | Omitted - no programmable VCC undervoltage lockout; VCC UVLO is fixed internally. |
| FAULT | Open-drain fault indicator | Pulls low during overcurrent fault; requires external pull-up; remains low until cooldown and INP toggle. |
| TIMER | Fault timing capacitor node | Connects to GND via CT (e.g., 1nF) to set warning, shutdown, and retry intervals; >3.5V disables timer. |
| INP | CMOS-compatible enable input | Active-high logic referenced to GND; internal 1MΩ pull-down holds TGDN=TS at startup. |
| OVLO | Not present on LTC7000-1 | Omitted - no input overvoltage lockout function; external protection required if needed. |
| ISET | Not present on LTC7000-1 | Omitted - current trip threshold fixed at 30mV; no resistor-programmable adjustment. |
| IMON | Not present on LTC7000-1 | Omitted - no current monitor output; feedback limited to FAULT and TIMER signals. |
| SNS+ | High-side current sense positive input | Kelvin-connected to shunt resistor; monitors drain current of external NMOS; ΔVSNS = VSNS+ – VSNS–. |
| SNS– | High-side current sense negative input | Connected via ≥100Ω resistor to shunt; forms differential pair with SNS+ for accurate overcurrent detection. |
| TGDN | High-current gate pull-down output | Drives external MOSFET gate to TS (high-side source); low-impedance path ensures fast turn-off. |
| TGUP | High-current gate pull-up output | Drives external MOSFET gate to BST (bootstrapped supply); tied directly to TGDN for fastest transition. |
| TS | High-side source reference node | Connects to MOSFET source; serves as local ground reference for SNS+, SNS–, TGUP, TGDN, and BST. |
| BST | Bootstrapped gate supply output | Swings from TS to (VIN + 12V); requires ≥0.1µF capacitor to TS for charge pump operation. |
| GND (Pin 17) | Thermal & electrical ground | Exposed pad; must be soldered to PCB plane for thermal dissipation and noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| 100% duty cycle support | Integrated charge pump maintains BST–TS ≥12V continuously - eliminates need for external bootstrap diode/capacitor circuits. |
| Fast switching performance | 35ns propagation delay + 13ns rise/fall times (CL = 1nF) - enables high-frequency (>1MHz) static switching and PWM control. |
| Robust overcurrent protection | Fixed 30mV current sense threshold with timer-based auto-retry - protects external MOSFET during sustained overload without latch-up. |
| High-voltage isolation capability | 16-lead MSOP package with 0.157mm creepage spacing - rated for 135V operation with reinforced insulation integrity. |
| Low quiescent current | 1µA shutdown current (via INP low) - minimizes standby power in battery-backed or energy-sensitive systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5109BMM/NOPB | Lower VIN max (100V), no internal charge pump (requires external bootstrap), no overcurrent timer or FAULT pin. | Lacks integrated fault management; suitable only for non-critical, low-duty-cycle switching where external protection is acceptable. | Select when cost sensitivity outweighs protection needs and 135V operation is unnecessary. |
| MAX17613ATP+ | Higher VIN max (150V), includes adjustable current limit and IMON, but uses SO-EP package (larger footprint, lower thermal performance). | Offers more configurability but lacks MSOP's compact size and 0.157mm HV spacing; requires layout revision for pin compatibility. | Choose when design requires programmable trip threshold and current monitoring, and board space allows SO-EP. |
Compared with LM5109BMM/NOPB and MAX17613ATP+, the LTC7000EMSE-1#TRPBF uniquely balances 135V operation, MSOP thermal efficiency, fixed 30mV overcurrent trip, and auto-retry fault handling - making it optimal for space-constrained industrial static switches needing reliable, maintenance-free protection.

FAQ
What is the maximum input voltage rating for the LTC7000EMSE-1#TRPBF?
The LTC7000EMSE-1#TRPBF has an absolute maximum VIN rating of 150V, with guaranteed operation from 3.5V to 135V. This allows direct integration into 120VAC-derived DC rails and 48V/60V industrial buses without pre-regulation. Exceeding 135V during normal operation risks violating the recommended operating conditions specified in the datasheet Rev. F.
Does the LTC7000EMSE-1#TRPBF support 100% duty cycle operation?
Yes, the LTC7000EMSE-1#TRPBF supports true 100% duty cycle operation via its integrated charge pump, which maintains BST–TS at ≥12V regardless of ON-time duration. This eliminates reliance on external bootstrap diodes or capacitors and enables continuous conduction mode in static switch and valve driver applications.
How does overcurrent protection work on the LTC7000EMSE-1#TRPBF?
The LTC7000EMSE-1#TRPBF detects overcurrent by comparing ΔVSNS across an external shunt to a fixed 30mV threshold. When exceeded, the TIMER capacitor begins charging; upon reaching 1.3V, FAULT asserts and TGDN pulls to TS after a programmable delay. After cooldown, the device automatically retries - no external reset is required.
Can the LTC7000EMSE-1#TRPBF drive GaN FETs effectively?
Yes, the LTC7000EMSE-1#TRPBF is well-suited for driving enhancement-mode GaN FETs due to its 35ns propagation delay, 1Ω pull-down strength, and 12V BST–TS gate drive voltage - all critical for minimizing switching losses and ensuring clean turn-off in MHz-range resonant converters.
What is the thermal performance of the LTC7000EMSE-1#TRPBF in its MSOP package?
The LTC7000EMSE-1#TRPBF in the 16-lead MSOP (MSE16) package has θJA = 45°C/W and θJC = 10°C/W when the exposed GND pad (Pin 17) is properly soldered to a PCB thermal plane. This enables reliable operation at full load up to +125°C ambient in typical industrial layouts with ≥2 oz copper and 4 thermal vias.
