Product details
Overview
LTC7000HMSE#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 power distribution systems requiring fast, protected high-side switching.
For engineers reviewing the LTC7000HMSE#TRPBF datasheet, LTC7000HMSE#TRPBF pinout, LTC7000HMSE#TRPBF application, or LTC7000HMSE#TRPBF equivalent, key selection criteria include its 135V VIN rating, 150°C junction temperature grade, integrated fault timer with automatic retry, adjustable current trip threshold via ISET, and thermally enhanced 16-lead MSOP package with exposed GND pad.
Technical Context
The LTC7000HMSE#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. Its current-sense comparator monitors ΔVSNS across an external sense resistor and triggers fault shutdown when ΔVTH (programmable 20–75mV) is exceeded.
It features dual-stage protection: fast overcurrent response (70ns propagation from sense step to TGDN low), configurable TIMER-based cooldown/retry timing, open-drain FAULT flag assertion, and thermal shutdown at ~180°C. The RUN pin enables precise undervoltage lockout control, while OVLO supports programmable input overvoltage detection.

The LTC7000HMSE#TRPBF is housed in a thermally enhanced 16-lead plastic MSOP package (MSE16) with exposed GND pad (Pin 17) that must be soldered to PCB for rated thermal performance (θJA = 45°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RUN (Pin 1) | Enable/UVLO Control Input | Enables operation above 1.21V; shuts down to ~1µA quiescent current below 0.7V; sets input UVLO via resistive divider. |
| 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 / Gate Driver Supply | 10V regulated output (or follows VIN if <10V); powers logic and drivers; can be overdriven externally for high-frequency use. |
| VCCUV (Pin 4) | VCC Undervoltage Lockout Reference | Sets VCC UVLO threshold (3.5V–7.0V) by scaling pin voltage ×7; short to GND for minimum threshold. |
| FAULT (Pin 5) | Open-Drain Fault Flag Output | Pulls low during overcurrent/fault condition; typical 200Ω pull-down impedance; remains asserted until cooldown completes. |
| TIMER (Pin 6) | Fault Timing Capacitor Node | Connects to GND via CT to set fault warning, shutdown, and auto-retry timing intervals. |
| INP (Pin 7) | CMOS-Compatible Control Input | Active-high logic input referenced to GND; internal 1MΩ pull-down ensures safe startup state. |
| OVLO (Pin 8) | Input Overvoltage Lockout Input | Triggers immediate TGDN-to-TS shutdown when voltage exceeds 1.21V; tied to GND if unused. |
| ISET (Pin 9) | Current Trip Threshold Programming | Sets ΔVTH = VISET/20 (20–75mV); short to GND for min 20mV; open for default 30mV. |
| IMON (Pin 10) | Analog Current Monitor Output | Ground-referenced 20× ΔVSNS voltage (0–1.5V); enables real-time load current feedback without isolation. |
| TGDN (Pin 11) | High-Current Gate Pull-Down | Directly pulls MOSFET gate to TS (high-side source); lowest-impedance path for fast turn-off. |
| TGUP (Pin 12) | High-Current Gate Pull-Up | Pulls MOSFET gate to BST (bootstrapped supply); ties to TGDN for maximum slew rate or adds series R for controlled dV/dt. |
| TS (Pin 13) | High-Side Source Reference | Return node for high-side switch; connects to MOSFET source; may be tied to GND in low-side configurations. |
| BST (Pin 14) | Bootstrapped Supply Rail | Output of internal charge pump; requires ≥0.1µF capacitor to TS; swings 12V above TS. |
| SNS– (Pin 15) | Negative Current Sense Input | Kelvin-connected to sense resistor low side; includes 100Ω series resistor for noise immunity. |
| SNS+ (Pin 16) | Positive Current Sense Input | Kelvin-connected to sense resistor high side; referenced to SNS– for accurate ΔVSNS measurement. |
| GND (Pin 17) | Exposed Thermal Pad / Ground | Must be soldered to PCB copper for thermal management and electrical grounding; primary heat dissipation path. |

FAQ
What is the maximum operating junction temperature for the LTC7000HMSE#TRPBF?
The LTC7000HMSE#TRPBF is rated for a maximum junction temperature of 150°C and is qualified for extended-temperature industrial and automotive applications. This rating is explicitly specified in the Order Information table and confirmed in Absolute Maximum Ratings (Note 2), distinguishing it from lower-grade variants like LTC7000EMSE#TRPBF (125°C). Operation beyond this limit risks permanent degradation.
Does the LTC7000HMSE#TRPBF support 100% duty cycle operation, and how is it achieved?
Yes, the LTC7000HMSE#TRPBF supports true 100% duty cycle operation via its integrated charge pump, which regulates the BST–TS voltage to 12V independent of duty cycle. As described in the "Internal Charge Pump" section (page 12), this eliminates reliance on external bootstrap capacitors that fail at high duty cycles - enabling continuous conduction in static switch and motor hold applications.
How does the IMON pin on the LTC7000HMSE#TRPBF function, and what is its voltage range?
The IMON pin on the LTC7000HMSE#TRPBF provides a ground-referenced analog output equal to 20× the voltage across the external sense resistor (ΔVSNS), with a linear range of 0V to 1.5V. Per Pin Functions (page 9) and Electrical Characteristics (page 6), this enables direct connection to microcontroller ADCs without isolation or level-shifting, supporting real-time load current monitoring in safety-critical systems.
What is the purpose of the RUN pin on the LTC7000HMSE#TRPBF, and how does it differ from the LTC7000-1 variant?
The RUN pin on the LTC7000HMSE#TRPBF enables precise enable/disable control and programmable input undervoltage lockout (UVLO) via a resistive divider. As stated in Pin Functions (page 9), pulling RUN below 0.7V reduces quiescent current to ~1µA. The LTC7000-1 variant omits this pin entirely - its operation starts automatically when VIN exceeds 3.5V, removing UVLO configurability but simplifying biasing.
Can the LTC7000HMSE#TRPBF drive GaN or SiC MOSFETs, and what gate drive strengths does it provide?
Yes, the LTC7000HMSE#TRPBF can drive GaN and SiC MOSFETs due to its 2.2Ω pull-up and 1Ω pull-down gate drive strength (Electrical Characteristics, page 5), fast 35ns propagation delay, and ability to handle high dV/dt transients. Its robust level-shifting architecture and 135V VIN rating make it suitable for high-frequency, high-efficiency topologies using wide-bandgap devices - provided gate voltage requirements (e.g., 0–6V for GaN) fall within the 12V BST–TS swing.
