Product details
Overview
LTC7000IMSE#WTRPBF from Analog Devices is a high-voltage, 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, delivers 2.2Ω pull-up / 1Ω pull-down gate drive strength, and features adjustable overcurrent protection with 35ns propagation delay. It is used in automotive-grade load switch and electronic valve control systems requiring fast turn-on/turn-off and robust fault management.
For engineers reviewing the LTC7000IMSE#WTRPBF datasheet, LTC7000IMSE#WTRPBF pinout, LTC7000IMSE#WTRPBF application, or LTC7000IMSE#WTRPBF equivalent, key selection considerations include its 135V VIN max rating, 16-lead MSOP thermal package with exposed GND pad, adjustable current trip via ISET pin, IMON current monitor output, and AEC-Q100 qualification for automotive environments.
Technical Context
The LTC7000IMSE#WTRPBF 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. Its logic-level INP input (CMOS-compatible, 1MΩ internal pull-down) controls TGUP/TGDN outputs referenced to TS, not GND.
Overcurrent protection uses a precision current-sense comparator monitoring ΔVSNS across an external shunt, with threshold ΔVTH programmable from 20mV to 75mV via ISET pin voltage. Fault response includes open-drain FAULT flag assertion, automatic retry after TIMER capacitor–defined cooldown, and immediate TGDN-to-TS shutdown in fast-fault mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Operating Range | 3.5V to 135V - supports wide-input industrial and automotive battery-fed systems without external regulators. |
| Gate Drive Strength | 2.2Ω pull-up / 1Ω pull-down - enables <13ns rise/fall times into 1nF load, minimizing switching losses in high-frequency or fast-transient applications. |
| Propagation Delay | 35ns - ensures precise timing alignment between INP command and TGUP/TGDN state change under load. |
| Current Sense Threshold | Adjustable 20mV–75mV ΔVTH - allows optimization of sense resistor value to balance accuracy, power loss, and noise immunity. |
| Charge Pump Output | Regulated 12V BST–TS - sustains full gate enhancement for 100% duty cycle operation without external bootstrap diode/capacitor complexity. |
| Operating Temperature | –40°C to +125°C junction - qualified per AEC-Q100 Grade I, suitable for under-hood automotive and harsh industrial environments. |
| Shutdown Current | 1µA - enables ultra-low-power standby in battery-critical systems when RUN pin is pulled low. |
Pinout & Package
The LTC7000IMSE#WTRPBF is housed in a thermally enhanced 16-lead plastic MSOP package (MSE16) with exposed GND pad (Pin 17), requiring PCB soldering for rated thermal performance (θJA = 45°C/W). High-voltage creepage is optimized for 150V abs max operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RUN (Pin 1) | Enable/UVLO Control Input | Enables operation above 1.21V; shuts down to ~1µA at <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 & Driver Supply | 10V regulated output (or follows VIN below dropout); 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) via resistor divider; prevents unreliable gate drive during low VCC. |
| FAULT (Pin 5) | Open-Drain Fault Flag Output | Pulls low when overcurrent detected; 200Ω typical pull-down; remains asserted until fault cooldown and reset. |
| TIMER (Pin 6) | Fault Timing Capacitor Node | Connects to GND via CT to set warning, shutdown, and retry intervals; >3.5V enables immediate fault shutdown. |
| INP (Pin 7) | CMOS-Compatible Control Input | Ground-referenced logic input; 1MΩ internal pull-down ensures safe default OFF state at startup. |
| OVLO (Pin 8) | Input Overvoltage Lockout Input | Triggers immediate TGDN-to-TS shutdown if VIN exceeds programmed threshold; tied to GND when unused. |
| ISET (Pin 9) | Current Trip Threshold Programming | Sets ΔVTH = VISET/20 (20–75mV); short to GND for min trip (20mV); open for nominal 30mV. |
| IMON (Pin 10) | Current Monitor Output | Ground-referenced 0–1.5V output = 20×ΔVSNS; enables real-time load current sensing without isolated amplifiers. |
| TGDN (Pin 11) | High-Current Gate Pull-Down | Directly connects to MOSFET gate; pulls to TS (not GND); enables fast, low-impedance turn-off. |
| TGUP (Pin 12) | High-Current Gate Pull-Up | Pulls to BST; ties to TGDN for fastest transition; series resistor optional for controlled dV/dt. |
| TS (Pin 13) | Top-Side Source Reference | High-side source node reference; may be connected to load return or GND in ground-referenced configurations. |
| BST (Pin 14) | Bootstrap Supply Rail | Connects to TS via ≥0.1µF capacitor; swing = 12V to (VIN + 12V); supplies TGUP during high-side conduction. |
| SNS– (Pin 15) | Current Sense Negative Input | Kelvin-connected to low-side of sense resistor; limits common-mode error and improves accuracy. |
| SNS+ (Pin 16) | Current Sense Positive Input | Kelvin-connected to high-side of sense resistor; differential input with 0.3V max common-mode range. |
| GND (Pin 17) | Exposed Thermal Pad / Ground | Mandatory PCB solder connection for thermal dissipation and electrical grounding; integral to θJC = 10°C/W spec. |
Key Features
| Feature | Design Value |
|---|---|
| 100% Duty Cycle Capability | Integrated charge pump maintains BST–TS at 12V regardless of VIN, eliminating bootstrap diode limitations in continuous-conduction applications. |

FAQ
What is the maximum input voltage rating for the LTC7000IMSE#WTRPBF?
The LTC7000IMSE#WTRPBF has an absolute maximum VIN rating of 150V and a specified operating range of 3.5V to 135V. This allows reliable operation in 48V, 60V, and 110V industrial and automotive battery systems while maintaining margin against transients. The TS and SNS+ pins also tolerate up to 150V, ensuring safe high-side sensing.
Does the LTC7000IMSE#WTRPBF support 100% duty cycle operation?
Yes, the LTC7000IMSE#WTRPBF supports true 100% duty cycle operation via its integrated charge pump, which regulates the BST–TS voltage to 12V independent of VIN. This eliminates reliance on external bootstrap diodes and capacitors, enabling continuous conduction in static switch applications such as electronic fuses and load switches.
How is overcurrent protection configured on the LTC7000IMSE#WTRPBF?
Overcurrent protection on the LTC7000IMSE#WTRPBF is configured using the ISET pin: connecting a resistor from ISET to GND sets ΔVTH = VISET/20, allowing adjustment from 20mV to 75mV. With ISET open, ΔVTH defaults to 30mV. The SNS+ and SNS– pins sense voltage across an external shunt resistor, and the comparator triggers fault action when ΔVSNS exceeds ΔVTH.
Is the LTC7000IMSE#WTRPBF AEC-Q100 qualified?
Yes, the LTC7000IMSE#WTRPBF is AEC-Q100 qualified for automotive applications (Grade I, –40°C to +125°C junction temperature). The "W" suffix in the part number denotes controlled manufacturing and testing per automotive reliability standards, including HTOL, ESD, and thermal cycling - confirmed in Analog Devices' official Automotive Reliability Reports.
What is the function of the IMON pin on the LTC7000IMSE#WTRPBF?
The IMON pin on the LTC7000IMSE#WTRPBF provides a ground-referenced analog output voltage equal to 20× the voltage across the external sense resistor (ΔVSNS), ranging from 0V to 1.5V. It enables real-time load current monitoring without isolation components, supporting diagnostics, closed-loop control, or system-level current logging in automotive and industrial applications.
