Product details
Overview
LTC7000IMSE#TRPBF from Analog Devices is a high-voltage, high-side N-channel MOSFET gate driver IC designed for static and high-frequency switching applications up to 135V input. It integrates an internal charge pump for 100% duty cycle operation, delivers 2.2Ω pull-up / 1Ω pull-down gate drive strength, achieves 35ns propagation delay, and provides adjustable overcurrent protection with current monitor output (IMON). It is used in industrial load switching, electronic valve control, and high-reliability supply rail management.
For engineers reviewing the LTC7000IMSE#TRPBF datasheet, LTC7000IMSE#TRPBF pinout, LTC7000IMSE#TRPBF application, or LTC7000IMSE#TRPBF equivalent, key selection criteria include its 135V VIN capability, fast 35ns propagation delay, integrated fault timer with automatic retry, adjustable current trip threshold via ISET pin, and thermally enhanced 16-lead MSOP package with exposed GND pad.
Technical Context
The LTC7000IMSE#TRPBF implements a level-shifted high-side driver architecture with integrated charge pump that regulates BST–TS to 12V, enabling indefinite conduction of external N-MOSFETs at up to 135V drain potential. Its dual-stage protection includes programmable overcurrent detection (ΔVTH = 20–75mV) using SNS+/SNS– differential sensing and a capacitor-set TIMER pin that defines fault warning, shutdown, and cooldown intervals.
It features CMOS-compatible INP input with 1MΩ internal pull-down, RUN pin-enabled startup sequencing (1.21V enable threshold), and independent VCCUV undervoltage lockout for gate drive supply (adjustable 3.5V–7.0V range). The IMON output (0–1.5V, 20× gain) provides real-time ground-referenced current monitoring - a feature exclusive to the LTC7000 (not LTC7000-1) variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Operating Range | 3.5V to 135V - supports wide-input industrial and automotive supply rails without external regulators. |
| Propagation Delay | 35ns (typ.) - enables precise timing control in high-frequency switching and fast transient response systems. |
| Gate Drive Strength | Pull-up: 2.2Ω; Pull-down: 1Ω - ensures rapid MOSFET turn-on/turn-off even with large gate capacitances (e.g., >1nF). |
| Current Sense Threshold | Adjustable 20–75mV ΔVSNS - sets overcurrent trip point via external resistor on ISET pin, minimizing sense resistor power loss. |
| IMON Output | 0–1.5V, 20× gain, ground-referenced - provides accurate analog current feedback for closed-loop monitoring or diagnostics. |
| Charge Pump Output | Regulated 12V BST–TS - sustains 100% duty cycle gate drive without external bootstrap diode or capacitor degradation. |
| Shutdown Current | 1µA (max) - enables ultra-low-power standby in battery-backed or energy-sensitive systems. |
Pinout & Package
Package: 16-lead plastic MSOP (MSE16) with exposed thermal pad (Pin 17 = GND), rated for –40°C to +125°C junction temperature. Exposed pad must be soldered to PCB for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RUN (1) | Enable/UVLO Control Input | Enables operation above 1.21V; shuts down IC below 0.7V (1µA quiescent); supports precision input UVLO via resistive divider. |
| VIN (2) | Main High-Voltage Supply Input | Accepts 3.5–135V; powers internal LDO and charge pump; requires ≥0.1µF bypass to GND. |
| VCC (3) | Internal LDO Output / Gate Driver Supply | 10V regulated output (or follows VIN if <10V); powers logic and drivers; can be overdriven externally for high-frequency use. |
| VCCUV (4) | VCC Undervoltage Lockout Reference | Sets gate drive UVLO threshold (3.5V–7.0V) by scaling pin voltage ×7; short to GND for minimum threshold. |
| FAULT (5) | Open-Drain Fault Flag Output | Pulls low when overcurrent detected; 200Ω typical pull-down; remains asserted until fault cooldown and reset. |
| TIMER (6) | Fault Timing Capacitor Interface | Connects to GND via CT to define fault warning, shutdown, and auto-retry intervals; >3.5V disables timer, forces immediate shutdown. |
| INP (7) | CMOS-Compatible Control Input | Ground-referenced logic input; 1MΩ internal pull-down ensures safe default state during startup. |
| OVLO (8) | Input Overvoltage Lockout Input | Triggers fault and disables output when VIN exceeds programmed threshold; tie to GND if unused. |
| ISET (9) | Current Trip Threshold Programming | Sets ΔVTH = VISET/20 (20–75mV); open = 30mV; grounded = 20mV; clamped 0.4–1.5V internally. |
| IMON (10) | Analog Current Monitor Output | Ground-referenced 0–1.5V output = 20×(VSNS+ − VSNS−); active only when TGUP is high; 100kΩ output impedance. |
| TGDN (11) | High-Current Gate Pull-Down | Directly pulls MOSFET gate to TS (high-side source); low 1Ω RDS(on) ensures fast turn-off. |
| TGUP (12) | High-Current Gate Pull-Up | Pulls MOSFET gate to BST (bootstrapped supply); 2.2Ω RDS(on); optional series resistor controls dV/dt. |
| TS (13) | High-Side Source Reference / Return | Connects to MOSFET source; serves as local ground reference for high-side gate drive and current sense. |
| BST (14) | Bootstrap Supply Node | Swings 12V above TS; requires ≥0.1µF capacitor to TS; supplies TGUP during high-side conduction. |
| SNS− (15) | Negative Current Sense Input | Low-impedance Kelvin connection point for sense resistor; must be routed with ≥100Ω series resistor. |
| SNS+ (16) | Positive Current Sense Input | Kelvin-connected to sense resistor high side; forms differential pair with SNS− for overcurrent detection. |
| GND (17) | Thermal & Electrical Ground | Exposed pad; must be soldered to PCB copper for thermal dissipation (θJA = 45°C/W) and signal integrity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side N-MOSFET gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5113SD/NOPB | Lower max VIN (100V), no integrated charge pump (requires external bootstrap), no IMON or ISET programming. | Lacks current monitoring and adjustable overcurrent trip; suited for cost-sensitive, non-diagnostic applications. | Select when 100V rating suffices and diagnostic features are unnecessary; requires external bootstrap components. |
| UCC27531DR | Max VIN = 20V, no high-side level shift or charge pump; designed for low-voltage half-bridge or single-ended drivers. | Cannot operate as high-side driver above ~20V; unsuitable for 48V+ industrial or automotive rails. | Only viable for low-voltage (<20V) ground-referenced gate driving; not a functional substitute for LTC7000IMSE#TRPBF. |
Compared with LM5113SD/NOPB, the LTC7000IMSE#TRPBF adds 35V higher voltage rating, integrated charge pump for 100% duty cycle, and diagnostic IMON/ISET features - making it superior for protected high-voltage static switching. UCC27531DR is incompatible due to fundamental voltage and topology limitations.

FAQ
What is the maximum input voltage rating for the LTC7000IMSE#TRPBF?
The LTC7000IMSE#TRPBF has an absolute maximum VIN rating of 150V and a specified operating range of 3.5V to 135V. This allows reliable operation in industrial 48V, 72V, and 110VDC systems with margin for transients. Operation beyond 135V is not guaranteed and may trigger internal protection or cause permanent damage.
Does the LTC7000IMSE#TRPBF support 100% duty cycle operation?
Yes, the LTC7000IMSE#TRPBF supports true 100% duty cycle operation via its integrated charge pump, which regulates the BST–TS voltage to 12V independently of input voltage or duty cycle. This eliminates reliance on external bootstrap diodes and capacitors, ensuring robust gate drive even during continuous conduction.
How does the IMON pin function on the LTC7000IMSE#TRPBF?
The IMON pin on the LTC7000IMSE#TRPBF provides a ground-referenced analog voltage equal to 20×(VSNS+ − VSNS−), ranging from 0V to 1.5V. It is active only when TGUP is high, offers 100kΩ output impedance, and enables direct connection to an ADC for real-time current monitoring without isolation or level-shifting circuitry.
What is the purpose of the ISET pin on the LTC7000IMSE#TRPBF?
The ISET pin on the LTC7000IMSE#TRPBF sets the overcurrent trip threshold voltage (ΔVTH) by dividing its voltage by 20. With ISET open, ΔVTH = 30mV; grounding ISET sets ΔVTH = 20mV; a resistor to GND allows adjustment between 20mV and 75mV - enabling precise matching to MOSFET RDS(on) and system safety margins.
Is the LTC7000IMSE#TRPBF pin-compatible with the LTC7000-1 variant?
No, the LTC7000IMSE#TRPBF (LTC7000) is not pin-compatible with LTC7000-1 variants. The LTC7000 includes RUN, OVLO, ISET, and IMON pins (Pins 1, 8, 9, 10), while LTC7000-1 omits them. Pinouts differ in functionality and assignment - direct substitution would require PCB redesign and firmware changes.
