Product details
Overview
LTC7000IMSE#PBF from Analog Devices is a high-voltage, fast-turn-on 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 for 100% duty cycle operation, features 2.2Ω pull-up / 1Ω pull-down gate drive strength, 35ns propagation delay, and adjustable overcurrent protection with current monitor output (IMON). It is used in industrial load switching, electronic valve control, and high-reliability supply sequencing.
For engineers reviewing the LTC7000IMSE#PBF datasheet, LTC7000IMSE#PBF pinout, LTC7000IMSE#PBF application, or LTC7000IMSE#PBF equivalent, key selection criteria include its 135V VIN capability, programmable current trip threshold via ISET pin, integrated fault timer with automatic retry, open-drain FAULT flag, and thermally enhanced 16-lead MSOP package with exposed GND pad.
Technical Context
The LTC7000IMSE#PBF implements a level-shifted high-side gate driver architecture with integrated charge pump that regulates BST–TS to ~12V, enabling indefinite conduction of external N-MOSFETs even at 100% duty cycle. Its current sense comparator monitors ΔVSNS across an external shunt resistor, triggering fault shutdown when threshold (20–75mV, set by ISET) is exceeded.
Operation includes configurable undervoltage lockouts on RUN (1.21V enable threshold), VCCUV (7× scaled UVLO), and OVLO pins; CMOS-compatible INP input with 1MΩ internal pull-down; and thermal shutdown at ~180°C junction temperature. The TIMER pin supports adjustable fault warning, turn-off, and cooldown timing via external capacitor.
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 regulation. |
| Gate Drive Strength | 2.2Ω pull-up / 1Ω pull-down - enables fast switching of large gate capacitances (e.g., 1nF load in ≤90ns). |
| Propagation Delay | 35ns - ensures precise timing alignment between INP command and TGUP/TGDN state change. |
| Current Sense Threshold | 20mV to 75mV (adjustable via ISET) - allows low-loss sensing with sub-mΩ shunts while maintaining accuracy. |
| Charge Pump Output | Regulated 12V BST–TS - sustains full gate enhancement for 100% duty cycle, eliminating shoot-through risk. |
| Fault Response | Open-drain FAULT pin + TIMER-cooled automatic retry - provides system-level fault signaling and self-recovery without host intervention. |
| Package Thermal Resistance | θJA = 45°C/W - enables reliable operation at 125°C junction temperature with standard PCB copper area. |
Pinout & Package
Package: 16-lead plastic MSOP (MSE16) with exposed GND pad (Pin 17), rated for –40°C to 125°C operating junction temperature. Exposed pad must be soldered to PCB for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RUN (Pin 1) | Enable/Shutdown Control | CMOS input; ≥1.21V enables operation, <0.7V forces shutdown (1µA IQ); also sets VIN 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 | 0.4–1.5V input scaled ×7 sets VCC UVLO threshold (3.5V–10.5V); short to GND = 3.5V UVLO. |
| FAULT (Pin 5) | Open-Drain Fault Flag Output | Pulls low when overcurrent detected and TIMER reaches 1.3V; typical 200Ω pull-down impedance. |
| TIMER (Pin 6) | Fault Timing Capacitor Node | External CT to GND sets fault warning, turn-off, and retry intervals; >3.5V disables timer and forces immediate TGDN pull-down. |
| INP (Pin 7) | CMOS-Compatible Input Signal | Controls TGUP/TGDN state; internal 1MΩ pull-down holds TGDN=TS during startup; rising edge initiates turn-on. |
| OVLO (Pin 8) | Input Overvoltage Lockout Input | Resistive divider from VIN sets OVLO threshold; >1.21V pulls TGDN=TS and asserts FAULT. |
| ISET (Pin 9) | Current Trip Threshold Programming | Resistor to GND sets ΔVTH = VISET/20 (20–75mV); open = 30mV default; enables low-loss current sensing. |
| IMON (Pin 10) | Current Monitor Output | Analog voltage = 20×(VSNS+–VSNS–), 0–1.5V range referenced to GND; only present on LTC7000 (not -1 variant). |
| TGDN (Pin 11) | High-Current Gate Pull-Down Output | Direct connection to MOSFET gate ensures fastest turn-off; pulls to TS (high-side source) with 1Ω resistance. |
| TGUP (Pin 12) | High-Current Gate Pull-Up Output | Connects to BST; ties to TGDN for maximum slew rate or adds series resistor for controlled dV/dt. |
| TS (Pin 13) | High-Side Source Reference / Return | Node tied to MOSFET source; serves as local ground reference for high-side driver and sense circuitry. |
| BST (Pin 14) | Bootstrapped Supply Rail | Output of internal charge pump; swing = 12V to (VIN + 12V); requires ≥0.1µF capacitor to TS. |
| SNS– (Pin 15) | Current Sense Negative Input | Kelvin-connected to shunt resistor; internal clamp limits SNS+–SNS– differential to ±0.3V continuous. |
| SNS+ (Pin 16) | Current Sense Positive Input | Kelvin-connected to shunt resistor; senses drain-side voltage for overcurrent detection. |
| GND (Pin 17) | Exposed Thermal Pad / System Ground | Mandatory solder connection to PCB ground plane 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 ≥12V indefinitely, enabling continuous conduction without external bootstrap diode/capacitor. |
| Programmable Overcurrent Protection | ISET pin allows precise setting of current trip threshold (20–75mV), reducing power loss and enabling use of ultra-low-Rshunt resistors. |
| Integrated Current Monitor (IMON) | Ground-referenced analog output (0–1.5V) proportional to sensed current (×20 gain), simplifying closed-loop current feedback design. |
| Configurable Fault Timing & Auto-Retry | TIMER pin accepts external capacitor to define fault warning window, shutdown delay, and cooldown period before automatic restart. |
| Multiple Protection Lockouts | Independent UVLO on RUN, VCCUV, and OVLO pins enables robust input supply monitoring and fail-safe shutdown under abnormal rail conditions. |
| Thermally Enhanced MSOP Package | 16-lead MSE16 with exposed GND pad delivers θJA = 45°C/W and supports 125°C continuous operation with standard layout. |

FAQ
What is the maximum input voltage rating for the LTC7000IMSE#PBF?
The LTC7000IMSE#PBF has an absolute maximum VIN rating of 150V and a specified operating range of 3.5V to 135V. This allows safe operation across wide industrial and automotive supply rails, including 24V, 48V, and 110V DC systems, while accommodating transients up to 150V without damage.
Does the LTC7000IMSE#PBF support 100% duty cycle operation?
Yes, the LTC7000IMSE#PBF supports true 100% duty cycle operation via its integrated charge pump, which regulates the BST–TS voltage to ~12V regardless of input voltage or conduction time. This eliminates the need for external bootstrap diodes or capacitors and ensures reliable gate enhancement for continuous conduction.
How does the current monitoring function work on the LTC7000IMSE#PBF?
The LTC7000IMSE#PBF provides a ground-referenced IMON output (Pin 10) that delivers a voltage equal to 20×(VSNS+–VSNS–), ranging from 0V to 1.5V. This analog signal enables real-time current measurement without additional amplification, supporting closed-loop control and diagnostics in applications like electronic valve drivers.
What is the purpose of the ISET pin on the LTC7000IMSE#PBF?
The ISET pin (Pin 9) on the LTC7000IMSE#PBF sets the current sense threshold voltage (ΔVTH) for overcurrent protection. A resistor from ISET to GND programs ΔVTH = VISET/20, allowing adjustment from 20mV to 75mV. This enables optimization of shunt resistor value and power loss while maintaining accurate trip detection.
Is the LTC7000IMSE#PBF pin-compatible with the LTC7000-1 variant?
No, the LTC7000IMSE#PBF is not pin-compatible with the LTC7000-1 variant. While both share the same 16-lead MSOP package, the LTC7000IMSE#PBF includes RUN, OVLO, ISET, and IMON pins (Pins 1, 8, 9, 10), whereas the LTC7000-1 omits these functions - resulting in different pin assignments and incompatible functionality for those features.
