Product details
Overview
LTC7000EMSE#TRPBF from Analog Devices is a high-voltage, fast-turning high-side N-channel MOSFET gate driver IC designed for static and switching high-side switch applications up to 135V input. It integrates an internal charge pump enabling 100% duty cycle operation, features 35ns propagation delay, 2.2Ω pull-up / 1Ω pull-down gate drive strength, and adjustable overcurrent protection with 30mV default current sense threshold. It is used in industrial power distribution systems requiring robust fault management and fast load switching.
For engineers reviewing the LTC7000EMSE#TRPBF datasheet, LTC7000EMSE#TRPBF pinout, LTC7000EMSE#TRPBF application, or LTC7000EMSE#TRPBF equivalent, key selection considerations include its 135V VIN capability, thermally enhanced 16-lead MSOP package with exposed GND pad, integrated fault timer and open-drain FAULT flag, adjustable VCC undervoltage lockout via VCCUV pin, and compatibility with external N-channel MOSFETs rated for ≥150V drain-source breakdown.
Technical Context
The LTC7000EMSE#TRPBF operates as a level-shifted, high-side gate driver with integrated charge pump that sustains BST–TS at 12V for indefinite conduction. Its logic-level INP input (CMOS-compatible, 1MΩ internal pull-down) controls TGUP/TGDN outputs referenced to TS, enabling direct drive of N-MOSFET gates in high-voltage floating configurations.
Overcurrent protection uses a precision current-sense comparator monitoring ΔVSNS across an external shunt, with trip threshold ΔVTH programmable from 20mV to 75mV via ISET pin. Fault response includes configurable TIMER-based cooldown/retry, open-drain FAULT assertion, and automatic TGDN pull-down to TS upon trip - all without requiring external microcontroller intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 3.5V to 135V - supports wide-input industrial and automotive supply rails; absolute max 150V. |
| Propagation Delay | 35ns - enables precise timing control in high-frequency switching or fast transient load switching. |
| Gate Drive Strength | 2.2Ω pull-up / 1Ω pull-down - delivers high peak current for rapid MOSFET turn-on/turn-off with minimal Miller plateau dwell. |
| Current Sense Threshold | Default 30mV ΔVTH (ISET open) - allows low-value sense resistors (e.g., 10mΩ for 3A trip), minimizing conduction loss. |
| Charge Pump Output | Regulated 12V BST–TS - sustains gate drive voltage for true 100% duty cycle operation without external bootstrap diode/capacitor complexity. |
| Operating Temp Range | –40°C to +125°C - qualified for extended industrial environments; junction max 150°C. |
| Package | 16-lead MSOP (MSE16) with exposed GND pad - provides low θJA = 45°C/W thermal resistance for high-power gate driving. |
Pinout & Package
Package: 16-lead plastic MSOP (MSE16), thermally enhanced with exposed GND pad (Pin 17) requiring PCB soldering for rated thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RUN (Pin 1) | Enable/UVLO Control Input | Enables internal LDO and logic when >1.21V; shuts down to ~1µA quiescent current when <0.7V - allows system-level power sequencing. |
| VIN (Pin 2) | Main High-Voltage Supply Input | Accepts 3.5V–135V; powers internal LDO (VCC) and charge pump - requires ≥0.1µF bypass to GND. |
| VCC (Pin 3) | Internal LDO Output / Gate Driver Supply | 10V regulated output (or follows VIN if <10V); powers drivers and logic - must not exceed VIN; decouple with ≥1µF ceramic cap. |
| VCCUV (Pin 4) | VCC Undervoltage Lockout Reference | Sets VCC UVLO threshold (×7 multiplier); short to GND = 3.5V UVLO, open = 7.0V UVLO - prevents unreliable gate drive during brownout. |
| FAULT (Pin 5) | Open-Drain Fault Flag Output | Pulls low when overcurrent detected and TIMER reaches 1.3V - signals impending TGDN-to-TS shutdown; ~200Ω pull-down impedance. |
| TIMER (Pin 6) | Fault Timing Capacitor Node | Connect CT to GND to set fault warning, shutdown, and auto-retry intervals - enables selective response to transient vs sustained overloads. |
| INP (Pin 7) | CMOS-Compatible Logic Input | Active-high control signal (1MΩ internal pull-down) - directly sets TGUP/TGDN state; defines switch ON/OFF timing with 35ns delay. |
| OVLO (Pin 8) | Input Overvoltage Lockout Input | Resistive divider from VIN sets OVLO threshold; >1.21V forces TGDN-to-TS shutdown - protects downstream loads from overvoltage. |
| ISET (Pin 9) | Current Trip Threshold Programming | Resistor to GND sets ΔVTH = VISET/20 (20–75mV range); open = 30mV default - enables precise, low-loss current limiting. |
| IMON (Pin 10) | Current Monitor Output | Analog voltage = 20×(VSNS+ – VSNS–), 0–1.5V range - provides isolated, ground-referenced current feedback for monitoring or closed-loop control. |
| TGDN (Pin 11) | High-Current Gate Pull-Down Output | Direct connection to MOSFET gate ensures fastest turn-off; pulls to TS (not GND) - essential for high-side configuration integrity. |
| TGUP (Pin 12) | High-Current Gate Pull-Up Output | Pulls to BST (not VCC); tie to TGDN for maximum slew rate - enables strong gate charging even at high TS potential. |
| TS (Pin 13) | Top-Side Source Reference | High-side source node connection point - serves as local ground reference for SNS+, SNS–, BST, TGUP, TGDN - must be low-impedance. |
| BST (Pin 14) | Bootstrap Supply Output | Charge pump output (BST–TS = 12V); requires ≥0.1µF capacitor to TS - sustains gate voltage above TS for 100% duty cycle. |
| SNS– (Pin 15) | Current Sense Negative Input | Kelvin-connected to low-side of sense resistor - minimizes error from trace resistance and noise coupling. |
| SNS+ (Pin 16) | Current Sense Positive Input | Kelvin-connected to high-side of sense resistor - forms differential pair with SNS– for accurate ΔVSNS measurement. |
| GND (Pin 17) | Exposed Thermal Pad / Ground Return | Mandatory soldered connection to PCB GND plane - critical 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 or switching frequency - eliminates need for external bootstrap diode/capacitor. |
| Adjustable Overcurrent Protection | ISET pin enables precise ΔVTH programming (20–75mV) - allows optimization of sense resistor value and power loss trade-offs. |
| Ground-Referenced Current Monitoring | IMON pin outputs 20×ΔVSNS (0–1.5V) referenced to system GND - simplifies ADC interfacing and eliminates need for isolated amplifiers. |
| Configurable Fault Response | TIMER capacitor sets fault warning window, shutdown delay, and auto-retry interval - supports both latching and self-recovering protection schemes. |
| High-Voltage Pin Spacing | MSE16 package variant offers 0.657mm creepage between high-voltage pins (VIN, TS, BST) - meets reinforced insulation requirements for 300VAC systems. |
| Thermal Robustness | Exposed GND pad + θJA = 45°C/W enables reliable operation at full 135V/3A continuous load without derating in standard PCB layouts. |

FAQ
What is the maximum input voltage rating for the LTC7000EMSE#TRPBF?
The LTC7000EMSE#TRPBF has an absolute maximum VIN rating of 150V, with guaranteed operation from 3.5V to 135V. This makes it suitable for demanding industrial and automotive applications where transient overvoltages up to 150V may occur. Exceeding 150V risks permanent damage per Absolute Maximum Ratings.
Does the LTC7000EMSE#TRPBF support 100% duty cycle operation?
Yes, the LTC7000EMSE#TRPBF supports true 100% duty cycle operation via its integrated charge pump, which regulates BST–TS to 12V independent of input voltage or switching frequency. This eliminates reliance on external bootstrap components and ensures reliable gate drive even during sustained conduction states.
How does overcurrent protection work on the LTC7000EMSE#TRPBF?
The LTC7000EMSE#TRPBF monitors ΔVSNS across an external sense resistor using a precision comparator. When ΔVSNS exceeds the ISET-programmed threshold (default 30mV), the TIMER capacitor initiates a fault sequence culminating in TGDN being pulled to TS. The FAULT pin asserts low to signal the condition, and auto-retry occurs after cooldown.
What is the purpose of the IMON pin on the LTC7000EMSE#TRPBF?
The IMON pin on the LTC7000EMSE#TRPBF provides a ground-referenced analog voltage equal to 20×(VSNS+ – VSNS–), ranging from 0V to 1.5V. It enables real-time current monitoring without isolation components, supporting diagnostics, closed-loop control, or load profiling in systems using the LTC7000EMSE#TRPBF.
Is the LTC7000EMSE#TRPBF pin-compatible with the LTC7000-1 variants?
No, the LTC7000EMSE#TRPBF (LTC7000) is not pin-compatible with LTC7000-1 variants. The LTC7000 includes RUN, OVLO, ISET, and IMON pins (Pins 1, 8, 9, 10), whereas LTC7000-1 omits them. Pin mapping differs significantly - using LTC7000-1 hardware with LTC7000 firmware or vice versa will result in functional failure.
