Product details
Overview
LTC7000EMSE-1#PBF from Analog Devices is a high-voltage, fast-turning high-side N-channel MOSFET gate driver IC designed for static and high-frequency switching applications up to 135V input. It features 1Ω pull-down / 2.2Ω pull-up gate drive strength, 35ns propagation delay, internal charge pump enabling 100% duty cycle operation, and integrated overcurrent protection with adjustable fault timer. It drives external high-side NMOS switches in industrial power distribution and electronic valve control.
For engineers reviewing the LTC7000EMSE-1#PBF datasheet, LTC7000EMSE-1#PBF pinout, LTC7000EMSE-1#PBF application, or LTC7000EMSE-1#PBF equivalent, key selection criteria include VIN range (3.5V–135V), BST-TS voltage capability (up to 14V), thermal performance in MSOP-16 package, absence of RUN/OVLO/ISET/IMON pins (LTC7000-1 variant), and compatibility with 0.007Ω sense resistors for 3A continuous load switching.
Technical Context
The LTC7000EMSE-1#PBF implements a level-shifted, high-side gate driver architecture with integrated charge pump that regulates BST-TS to 12V (typ.) across 3.5V–135V VIN. Its logic-level INP input controls TGUP/TGDN outputs referenced to TS, enabling direct drive of NMOS switches with source at up to 150V above GND.
Overcurrent protection operates via SNS+/SNS− differential sensing with fixed 30mV threshold (ISET open), triggering fault flag assertion and automatic retry after cooldown. Unlike the LTC7000, the -1 variant omits RUN, OVLO, ISET, and IMON pins-simplifying layout but removing programmable UVLO/OVLO, current trip adjustment, and analog current monitoring.
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 |
| Max Absolute VIN | 150V - defines safe operating margin for transient suppression design |
| TG Pull-Down R | 1Ω - enables sub-50ns turn-off into 1nF gate capacitance, critical for fast fault response |
| TG Pull-Up R | 2.2Ω - ensures rapid MOSFET turn-on while limiting inrush current during bootstrapping |
| Propagation Delay | 35ns - guarantees tight timing control in high-frequency (>1MHz) switching topologies |
| Charge Pump Output | 12V BST-TS (typ.) - sustains full gate enhancement for 100% duty cycle NMOS conduction |
| Operating Temp | –40°C to +125°C - qualified for industrial ambient environments with derated lifetime above 125°C |
Pinout & Package
Package: 16-lead plastic MSOP (MSE16), thermally enhanced with exposed GND pad (Pin 17). High-voltage creepage spacing: 0.157mm between adjacent pins; recommended for ≤135V operation.
| 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; powers logic and gate drivers; can be overdriven externally for high-frequency use |
| FAULT (Pin 5) | Open-drain fault indicator | Pulls low when overcurrent detected; 200Ω typical pull-down; signals impending TGDN-to-TS shutdown |
| INP (Pin 7) | CMOS-compatible enable input | Active-high logic control (VIH = 1.7V min); internal 1MΩ pull-down holds TGDN low at startup |
| TGDN (Pin 11) | High-current gate pull-down output | Directly connects to MOSFET gate; pulls to TS (not GND); enables fast turn-off under fault |
| TGUP (Pin 12) | High-current gate pull-up output | Drives gate toward BST; ties to TGDN for fastest transition; resistor optional for slew control |
| TS (Pin 13) | High-side source reference | Connects to MOSFET source; serves as local ground reference for gate drive and sensing |
| BST (Pin 14) | Bootstrap supply node | Connects to TS via ≥0.1µF capacitor; swings from TS to (VIN + 12V); supplies TGUP drive voltage |
| SNS+ (Pin 16) | Current sense positive input | Kelvin-connected to sense resistor high side; used with SNS− for ΔVSNS measurement |
| GND (Pin 17) | Thermal & electrical ground | Exposed pad must be soldered to PCB plane for θJA = 45°C/W and EMI/thermal integrity |
Key Features
| Feature | Design Value |
|---|---|
| 100% Duty Cycle Support | Integrated charge pump maintains BST-TS ≥12V regardless of VIN, enabling indefinite NMOS conduction |
| Fast Fault Response | 35ns propagation delay + 70ns overcurrent-to-TGDN-low delay ensures <100ns total fault reaction time |
| High-Voltage Isolation | MSOP-16 package with 0.157mm pin spacing rated for 135V continuous operation per JEDEC standards |
| Robust Gate Drive | 1Ω pull-down / 2.2Ω pull-up delivers >1A peak current into gate capacitance for <20ns rise/fall times (CL=1nF) |
| Auto-Retry Protection | External TIMER capacitor sets fault warning, shutdown, and cooldown intervals; enables self-recovery after transient overloads |

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 |
|---|---|---|---|
| LM5109BMM/NOPB | No integrated charge pump; requires external bootstrap diode/capacitor; max VIN = 100V; no built-in overcurrent timer | Lacks auto-retry and fixed 30mV current sense; suitable only where external fault logic is acceptable | Select when cost sensitivity outweighs integration benefits and VIN ≤100V |
| MAX15062ATA+ | Includes charge pump but lacks SNS+/SNS− inputs; uses internal current sense; max VIN = 65V; no FAULT pin | Not suitable for precision external shunt-based current limiting; limited to lower-voltage applications | Choose only for ≤65V systems where integrated sense suffices and fault signaling is not required |
Compared with LM5109BMM/NOPB and MAX15062ATA+, the LTC7000EMSE-1#PBF uniquely combines 135V operation, integrated charge pump, fixed 30mV current threshold, open-drain FAULT output, and auto-retry timer in a single MSOP-16 package-making it optimal for robust, high-voltage static switching where layout simplicity and fault autonomy are critical.

FAQ
What is the maximum input voltage rating for the LTC7000EMSE-1#PBF?
The LTC7000EMSE-1#PBF has an absolute maximum VIN rating of 150V, with guaranteed operation from 3.5V to 135V. This allows reliable use in industrial 48V, 72V, and 100V bus systems, including transient-tolerant designs where 135V represents the continuous operational ceiling per datasheet specifications.
Does the LTC7000EMSE-1#PBF support 100% duty cycle operation?
Yes, the LTC7000EMSE-1#PBF supports true 100% duty cycle operation via its internal charge pump, which maintains BST-TS at ~12V regardless of VIN level. This ensures continuous enhancement of the external high-side NMOS switch without gate drive collapse-critical for static switch and hold-mode applications.
How does overcurrent protection work in the LTC7000EMSE-1#PBF?
The LTC7000EMSE-1#PBF monitors voltage across an external sense resistor via SNS+/SNS− inputs. With ISET open, it uses a fixed 30mV threshold (ΔVTH). When exceeded, the FAULT pin asserts low after a delay set by the TIMER capacitor, then pulls TGDN to TS to disable the MOSFET. After cooldown, it automatically retries.
What is the purpose of the TS pin on the LTC7000EMSE-1#PBF?
The TS pin on the LTC7000EMSE-1#PBF serves as the high-side source reference node-connected directly to the source terminal of the external NMOS switch. All gate drive outputs (TGUP, TGDN), current sense inputs (SNS+, SNS−), and BST are referenced to TS, enabling true high-side operation with source potentials up to 150V above system ground.
Is the LTC7000EMSE-1#PBF pin-compatible with the LTC7000EMSE#PBF?
No, the LTC7000EMSE-1#PBF is not pin-compatible with the LTC7000EMSE#PBF. The -1 variant omits RUN, OVLO, ISET, and IMON pins (Pins 1, 8, 9, 10), reallocating those positions to no-connect. Layouts designed for the standard LTC7000 require redesign to accommodate the reduced pin count and different functionality of the LTC7000EMSE-1#PBF.
