Product details
Overview
LTC7000EMSE#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 an internal charge pump enabling 100% duty cycle operation, 35ns propagation delay, 1Ω pull-down / 2.2Ω pull-up gate drive strength, and adjustable overcurrent protection with current monitor output. It is used in industrial load switch and electronic valve control systems requiring robust fault management.
For engineers reviewing the LTC7000EMSE#PBF datasheet, LTC7000EMSE#PBF pinout, LTC7000EMSE#PBF application, or LTC7000EMSE#PBF equivalent, key selection criteria include its 135V VIN capability, 16-lead MSOP thermal package, integrated current sense threshold adjustment (ISET), IMON analog current monitoring, and RUN/OVLO pin support for programmable undervoltage/overvoltage lockouts.
Technical Context
The LTC7000EMSE#PBF implements a level-shifted high-side gate driver architecture with integrated charge pump regulation (BST–TS = 12V typical), enabling continuous conduction without external bootstrap diode or capacitor recharging limitations. Its current-sense comparator uses SNS+/SNS– differential inputs referenced to TS, with ΔVTH programmable via ISET (20mV–75mV) and internally clamped.
Operation includes three-stage fault response: early-warning FAULT assertion at TIMER = 1.3V, TGDN forced low after cooldown, then automatic retry with configurable duty cycle (e.g., 0.1% with 1nF CTIMER). The RUN pin enables precise startup sequencing and UVLO, while OVLO provides independent input overvoltage protection - both absent in the LTC7000-1 variant.
Key Specifications

Pinout & Package
Package: 16-Lead Plastic MSOP (MSE16), 0.157mm high-voltage pin spacing, exposed GND pad (Pin 17) required for 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 when <0.7V; supports resistive divider for precise input UVLO. |
| 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 drivers and logic; can be overdriven externally for high-frequency use. |
| VCCUV (Pin 4) | VCC Undervoltage Lockout Reference | Sets VCC UVLO threshold (3.5V–7.0V) via resistor divider; short to GND for minimum 3.5V lockout. |
| FAULT (Pin 5) | Open-Drain Fault Flag Output | Pulls low when TIMER reaches 1.3V; indicates imminent TGDN turn-off due to overcurrent; 200Ω typical pull-down impedance. |
| TIMER (Pin 6) | Fault Timing Capacitor Node | Connects to GND via CTIMER to set warning, shutdown, and retry intervals; pulled >3.5V disables timer and forces immediate fault response. |
| INP (Pin 7) | CMOS-Compatible Control Input | Ground-referenced digital input controlling TGUP/TGDN state; includes 1MΩ internal pull-down for safe startup. |
| OVLO (Pin 8) | Input Overvoltage Lockout Input | Resistive divider from VIN sets OVLO threshold; >1.21V triggers fault and pulls TGDN to TS; tie to GND if unused. |
| ISET (Pin 9) | Current Trip Threshold Programming | Resistor to GND sets ΔVTH (20mV–75mV); open = 30mV default; enables precision current limiting with low-loss sensing. |
| IMON (Pin 10) | Analog Current Monitor Output | Ground-referenced 0–1.5V output = 20× (VSNS+ – VSNS–); active only when TGUP is high; 100kΩ output impedance. |
| TGDN (Pin 11) | High-Current Gate Pull-Down Output | Directly drives MOSFET gate to TS (high-side source); 1Ω on-resistance enables fast turn-off even under high dV/dt. |
| TGUP (Pin 12) | High-Current Gate Pull-Up Output | Drives MOSFET gate to BST (bootstrap rail); 2.2Ω on-resistance; optional series resistor controls turn-on slew rate. |
| TS (Pin 13) | High-Side Source Reference | Connects to MOSFET source; serves as local ground reference for SNS+, SNS–, TGUP, TGDN, and BST. |
| BST (Pin 14) | Bootstrap Supply Rail | Charge pump output (BST–TS ≈ 12V); requires ≥0.1µF capacitor to TS; swing spans 12V to (VIN + 12V). |
| SNS– (Pin 15) | Negative Current Sense Input | Differential input for sense resistor; connected via ≥100Ω resistor to minimize noise coupling and ESD risk. |
| SNS+ (Pin 16) | Positive Current Sense Input | Kelvin-connected to sense resistor; forms ΔVSNS with SNS–; comparator trips when ΔVSNS > ΔVTH. |
| GND (Pin 17) | Exposed Thermal Pad / System Ground | Mandatory solder connection to PCB ground plane for thermal dissipation (θJC = 10°C/W) and signal integrity. |
Key Features

FAQ
What is the maximum input voltage rating for the LTC7000EMSE#PBF?
The LTC7000EMSE#PBF has an absolute maximum VIN rating of 150V and a specified operating range of 3.5V to 135V. Operation beyond 135V is not guaranteed and may trigger internal protection or cause permanent damage. The device's 0.157mm high-voltage pin spacing supports reinforced insulation for 135V DC applications per IEC 62368-1.
Does the LTC7000EMSE#PBF support 100% duty cycle operation?
Yes, the LTC7000EMSE#PBF supports true 100% duty cycle operation using its integrated charge pump, which maintains BST–TS at ~12V regardless of input voltage or switching frequency. This eliminates reliance on external bootstrap capacitor recharge cycles - a key differentiator from non-charge-pump gate drivers like the LM5109B.
How is overcurrent protection configured on the LTC7000EMSE#PBF?
Overcurrent protection on the LTC7000EMSE#PBF is configured via the ISET pin: connecting a resistor from ISET to GND sets the current sense threshold ΔVTH from 20mV to 75mV (ΔVTH = VISET/20). An open ISET defaults to 30mV. The SNS+/SNS– differential inputs monitor the sense resistor voltage, and the TIMER capacitor determines fault timing behavior.
What is the function of the IMON pin on the LTC7000EMSE#PBF?
The IMON pin on the LTC7000EMSE#PBF provides a ground-referenced analog voltage output equal to 20× the voltage across the external sense resistor (VSNS+ – VSNS–), ranging from 0V to 1.5V. It is active only when TGUP is high and includes 100kΩ internal pull-down when INP is low - enabling direct microcontroller ADC monitoring without level-shifting circuitry.
Is the LTC7000EMSE#PBF pin-compatible with the LTC7000-1 variant?
No, the LTC7000EMSE#PBF is not pin-compatible with the LTC7000-1. The LTC7000EMSE#PBF includes RUN, OVLO, ISET, and IMON pins (Pins 1, 8, 9, 10), whereas the LTC7000-1 omits these four pins and repurposes their locations. Board designs must be modified to accommodate the full-feature LTC7000EMSE#PBF versus the simplified LTC7000-1 variant.
