Product details
Overview
LTC7004IMSE#TRPBF from Analog Devices is a fast 60V high-side N-channel MOSFET gate driver with internal charge pump enabling 100% duty cycle operation. It delivers 1Ω pull-down and 2.2Ω pull-up drive strength, 35ns propagation delay, and supports input voltages from 0V to 60V - ideal for automotive load switch and electronic valve control where fast, robust high-voltage switching is required.
For engineers reviewing the LTC7004IMSE#TRPBF datasheet, LTC7004IMSE#TRPBF pinout, LTC7004IMSE#TRPBF application, or LTC7004IMSE#TRPBF equivalent, key selection criteria include its 60V TS voltage rating, adjustable VCC undervoltage lockout via VCCUV pin, programmable OVLO threshold, gate drive slew rate control, and AEC-Q100 qualification for automotive use.
Technical Context
The LTC7004IMSE#TRPBF integrates a high-voltage level shifter and charge pump that regulates BST–TS to 12V, enabling indefinite conduction of external high-side NMOS switches. Its dual-output architecture separates TGUP (pull-up to BST) and TGDN (pull-down to TS), allowing independent control of turn-on slew rate via external series resistance on TGUP.
Protection logic includes three independent undervoltage lockouts: VCCUV-configurable VCC UVLO (3.5V–10.5V), BST–TS floating UVLO (3.1V), and OVLO pin-based input overvoltage detection (1.11V–1.21V threshold). All operate by forcing TGDN to TS, ensuring fail-safe shutdown under fault conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range (TS) | 0V to 60V - supports direct connection to automotive battery rails and industrial 48V systems without external level-shifting. |
| TG Pull-Down Resistance | 1Ω typical - ensures rapid MOSFET turn-off even with large gate capacitance (e.g., >1nF), minimizing shoot-through risk in high-frequency switching. |
| TG Pull-Up Resistance | 2.2Ω typical - enables controlled gate charging; combined with external series resistor on TGUP, allows precise inrush current limiting during power-up. |
| Propagation Delay | 35ns typical - guarantees sub-50ns timing response from INP edge to TG output transition, critical for synchronous rectification and fast protection circuits. |
| Charge Pump Output | Regulates BST–TS to 12V - sustains full gate overdrive (VGS) across entire duty cycle, eliminating gate droop and maintaining low RDS(ON) in high-side NMOS. |
| Operating Junction Temp | –40°C to +125°C - qualified per AEC-Q100 Grade I, suitable for under-hood automotive modules and industrial motor drives. |
| Package Thermal Impedance | θJA = 45°C/W - requires exposed pad soldering to PCB ground plane to achieve rated power dissipation and reliability. |
Pinout & Package
Delivered in thermally enhanced 10-lead MSOP package (MSE) with exposed GND pad (Pin 11) requiring PCB soldering for electrical integrity and thermal performance. Package dimensions: 3.0mm × 3.0mm × 0.86mm, pitch 0.5mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Main supply input | Accepts 3.5V–15V; powers internal logic and charge pump; bypass capacitor ≥0.1µF required to GND. |
| VCCUV (Pin 2) | VCC undervoltage lockout reference | Resistor-to-GND sets rising VCC UVLO threshold between 3.5V and 10.5V; open = 7.0V default. |
| GND (Pin 3 & Exposed Pad Pin 11) | Ground reference and thermal path | Exposure pad must be soldered to PCB ground plane for θJA = 45°C/W and ESD/EMI immunity. |
| INP (Pin 4) | CMOS-compatible digital input | Drives internal logic; 1MΩ internal pull-down holds TGDN low at startup; VIH = 2.0V, VIL = 1.6V, 400mV hysteresis. |
| OVLO (Pin 5) | Input overvoltage detection input | Resistive divider from VIN sets lockout threshold; >1.21V pulls TGDN to TS; tied to GND if unused. |
| TGDN (Pin 6) | High-current gate pull-down output | Directly connects to MOSFET gate for fastest turn-off; sinks current to TS (not GND) - essential for high-side configuration. |
| TGUP (Pin 7) | High-current gate pull-up output | Connects to MOSFET gate via optional series resistor to control turn-on slew rate; sources current from BST. |
| TS (Pin 8) | High-side source reference | Connects to MOSFET source terminal; tolerates –6V to +65V; serves as local ground reference for driver outputs. |
| BST (Pin 9) | Bootstrapped supply output | Charged by internal pump to maintain BST–TS = 12V; requires ≥0.1µF capacitor to TS for stable gate drive. |
| NC (Pin 10) | No-connect | Must be left floating; no internal connection or function. |
Key Features
| Feature | Design Value |
|---|---|
| 100% duty cycle support | Internal charge pump maintains BST–TS = 12V continuously, enabling indefinite high-side NMOS conduction without gate voltage collapse. |
| Adjustable turn-on slew rate | External resistor on TGUP limits dV/dt at MOSFET gate, reducing EMI and inrush current into large capacitive loads (e.g., 15mF bus capacitance). |
| Triple-stage undervoltage/overvoltage protection | Independent lockouts on VCC, BST–TS, and VIN ensure safe shutdown before gate drive becomes insufficient or input exceeds safe operating area. |
| AEC-Q100 Grade I qualification | Validated for automotive applications including body control modules, battery disconnect units, and electronic valve drivers operating at –40°C to +125°C. |
| High dv/dt immune level shifting | Proprietary level shifter withstands >50V/ns transients on TS node, preventing false triggering when driving inductive loads at 60V. |

FAQ
What is the maximum TS voltage rating for the LTC7004IMSE#TRPBF?
The LTC7004IMSE#TRPBF supports TS voltages from –6V to +65V absolute maximum, with continuous operation specified from 0V to +60V. This enables direct interface with 48V automotive systems and industrial 60V DC rails without external level-shifting circuitry. The device's internal level shifter and charge pump remain fully functional across this range, and the –6V negative tolerance accommodates inductive kickback during MOSFET turn-off.
How does the LTC7004IMSE#TRPBF achieve 100% duty cycle operation?
The LTC7004IMSE#TRPBF achieves 100% duty cycle using an internal charge pump that actively regulates the BST–TS voltage to 12V regardless of duty cycle or switching frequency. Unlike passive bootstrap circuits that collapse during extended ON periods, this regulated charge pump sustains full gate overdrive (VGS) on the external NMOS, ensuring low RDS(ON) and reliable conduction - critical for static switch applications like battery disconnects.
Can the LTC7004IMSE#TRPBF drive both enhancement-mode and depletion-mode MOSFETs?
The LTC7004IMSE#TRPBF is designed exclusively for enhancement-mode N-channel MOSFETs. Its TGUP output sources current from BST (not VCC), and TGDN sinks current to TS - a topology optimized for high-side NMOS gate control. Depletion-mode devices require negative gate bias or constant-current drive not supported by the LTC7004IMSE#TRPBF's output architecture or protection logic.
What is the purpose of the NC pin (Pin 10) on the LTC7004IMSE#TRPBF?
Pin 10 of the LTC7004IMSE#TRPBF is designated NC (No Connect) and has no internal connection. It must be left electrically floating - neither tied to GND nor routed - to prevent parasitic coupling or unintended current paths. This pin exists solely for mechanical symmetry in the MSOP package and plays no role in electrical functionality, thermal management, or ESD protection.
Does the LTC7004IMSE#TRPBF require an external bootstrap diode?
The LTC7004IMSE#TRPBF does not require an external bootstrap diode under normal operation due to its integrated charge pump. However, an external silicon diode (e.g., BAS116) from VCC to BST is recommended if power-up time to full gate drive exceeds 40ms or if switching frequency exceeds ~500Hz - conditions where the internal 30µA charge pump current may be insufficient to maintain BST–TS regulation.
