Product details
Overview
LTC7000MPMSE#PBF 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 features an internal charge pump enabling 100% duty cycle operation, 35ns propagation delay, 2.2Ω pull-up / 1Ω pull-down gate drive strength, and adjustable overcurrent protection with 30mV default current sense threshold. It is used in industrial power distribution systems requiring fast, protected high-side switching.
For engineers reviewing the LTC7000MPMSE#PBF datasheet, LTC7000MPMSE#PBF pinout, LTC7000MPMSE#PBF application, or LTC7000MPMSE#PBF equivalent, key selection criteria include its –55°C to 150°C extended temperature rating, MSOP-16 (MSE16) package with exposed GND pad, integrated fault timer and open-drain FAULT flag, and compatibility with external N-channel MOSFETs rated up to 150V drain-source voltage.
Technical Context
The LTC7000MPMSE#PBF implements a level-shifted, high-side gate driver architecture with integrated charge pump regulation (BST–TS = 12V typical), enabling continuous conduction without bootstrap capacitor recharge limitations. Its current-sense comparator monitors ΔVSNS across an external shunt resistor and triggers fault shutdown after programmable delay set by CTIMER.
It supports dual-mode protection: adjustable overcurrent trip via ISET pin (20–75mV threshold), and automatic retry with cooldown period. The RUN pin enables precise VIN undervoltage lockout (UVLO) and overvoltage lockout (OVLO) control via external resistive dividers - functionality absent in the LTC7000-1 variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 3.5V to 135V - supports wide-input industrial and automotive supply rails without external regulators. |
| Propagation Delay | 35ns - ensures tight timing control in high-frequency switching and fast transient response systems. |
| Gate Drive Strength | Pull-up: 2.2Ω; Pull-down: 1Ω - delivers high peak current for rapid MOSFET turn-on/turn-off, minimizing switching losses. |
| Current Sense Threshold | Default 30mV (ISET open) - enables low-value sense resistors (e.g., 0.007Ω at 4.3A), reducing power loss and thermal stress. |
| Operating Temp Range | –55°C to 150°C - qualified for harsh-environment applications including aerospace, downhole, and military-grade power systems. |
| Charge Pump Output | Regulated 12V (BST–TS) - sustains full gate drive voltage for 100% duty cycle, eliminating bootstrap diode/capacitor dependency. |
| Fault Response | Open-drain FAULT output + TIMER pin with 1.3V threshold - provides early warning and configurable fault hold-off before forced TGDN-to-TS shutdown. |
Pinout & Package
Package: 16-lead plastic MSOP (MSE16) with exposed thermal pad (Pin 17 = GND), optimized for high-voltage creepage (0.157mm pin spacing) and thermal performance (θJA = 45°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RUN (Pin 1) | Enable/UVLO/OVLO control input | Enables operation above 1.21V; sets precise VIN lockout thresholds via external divider - not present on LTC7000-1 variants. |
| 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 <10V); powers logic and drivers - must not exceed VIN. |
| VCCUV (Pin 4) | VCC undervoltage lockout reference | Sets gate-drive UVLO threshold (×7 multiplier); short to GND = 3.5V UVLO, open = 7.0V UVLO. |
| FAULT (Pin 5) | Open-drain fault indicator | Pulls low when TIMER reaches 1.3V - signals imminent overcurrent shutdown; 200Ω typical pull-down impedance. |
| TIMER (Pin 6) | Fault timing capacitor connection | CT to GND sets warning time, shutdown delay, and auto-retry interval - connect >3.5V for immediate fault response. |
| INP (Pin 7) | CMOS-compatible enable input | Active-high logic input referenced to GND; internal 1MΩ pull-down holds TGDN low during startup. |
| OVLO (Pin 8) | Input overvoltage lockout input | Triggers immediate fault if VIN exceeds programmed threshold - tie to GND if unused. |
| ISET (Pin 9) | Current trip threshold programming | Sets ΔVTH = VISET/20 (20–75mV); open = 30mV default - enables precise current limiting without calibration. |
| IMON (Pin 10) | Analog current monitor output | Ground-referenced 20× amplified SNS+–SNS– voltage (0–1.5V range) - only available on LTC7000 (not -1). |
| TGDN (Pin 11) | High-current gate pull-down | Directly connects to MOSFET gate; pulls to TS (high-side source) - critical for fast turn-off in high-dV/dt environments. |
| TGUP (Pin 12) | High-current gate pull-up | Pulls to BST (bootstrapped supply); ties to TGDN for fastest transition - series resistor controls dV/dt. |
| TS (Pin 13) | High-side source reference | Connects to MOSFET source terminal - serves as local ground reference for high-side sensing and drive. |
| BST (Pin 14) | Bootstrapped supply rail | Swings from ~12V to (VIN + 12V); requires ≥0.1µF capacitor to TS - enables 100% duty cycle gate drive. |
| SNS– (Pin 15) | Current sense negative input | Kelvin-connected to shunt resistor - minimizes PCB trace resistance error in precision current measurement. |
| SNS+ (Pin 16) | Current sense positive input | Kelvin-connected to shunt resistor - forms differential pair with SNS– for accurate ΔVSNS detection. |
| GND (Pin 17) | Exposed thermal pad | Must be soldered to PCB copper pour - essential for thermal dissipation (θJC = 10°C/W) and electrical grounding. |
Key Features
| Feature | Design Value |
|---|---|
| 100% Duty Cycle Operation | Integrated charge pump maintains BST–TS = 12V regardless of VIN, enabling indefinite high-side conduction without bootstrap recharge. |
| Adjustable Overcurrent Protection | ISET pin programs current trip threshold from 20mV to 75mV - allows optimization of sense resistor value and power loss trade-offs. |
| Early Fault Warning | Open-drain FAULT pin asserts before TGDN turns off, enabling system-level diagnostics and graceful load shedding prior to shutdown. |
| Extended Temperature Rating | –55°C to 150°C operating range - validated for mission-critical applications where standard industrial grade (–40°C to 125°C) is insufficient. |
| High-Voltage Pin Spacing | 0.157mm creepage distance between pins - meets reinforced insulation requirements for 135V DC systems per IEC 60950/62368. |

FAQ
What is the maximum input voltage rating for the LTC7000MPMSE#PBF?
The LTC7000MPMSE#PBF has an absolute maximum VIN rating of 150V and a recommended operating range of 3.5V to 135V. Exceeding 150V may cause permanent damage. This rating applies across its full –55°C to 150°C junction temperature range, verified per Analog Devices' high-reliability qualification standards.
Does the LTC7000MPMSE#PBF support 100% duty cycle operation?
Yes, the LTC7000MPMSE#PBF supports true 100% duty cycle operation via its integrated charge pump, which regulates BST–TS to 12V regardless of input voltage or duty cycle. This eliminates reliance on external bootstrap components and enables continuous conduction in static switch applications - a core design feature confirmed in the device's block diagram and electrical characteristics table.
How does the current sense function work on the LTC7000MPMSE#PBF?
The LTC7000MPMSE#PBF uses differential inputs SNS+ and SNS– to monitor voltage across an external sense resistor. Its internal comparator trips when ΔVSNS exceeds ΔVTH, which defaults to 30mV (ISET open) and is programmable from 20mV to 75mV via the ISET pin. This directly controls overcurrent shutdown timing and is independent of VIN or temperature drift per published performance curves.
What is the purpose of the IMON pin on the LTC7000MPMSE#PBF?
The IMON pin on the LTC7000MPMSE#PBF provides a ground-referenced analog output voltage equal to 20× the voltage across the external sense resistor (SNS+–SNS–), ranging from 0V to 1.5V. It is active only when TGUP is high and INP is asserted, enabling real-time current monitoring without additional amplification - a feature exclusive to the LTC7000 (not LTC7000-1) variants.
Is the LTC7000MPMSE#PBF pin-compatible with other variants in the LTC7000 family?
Yes, the LTC7000MPMSE#PBF shares identical pinout and package (16-lead MSOP, MSE16) with all LTC7000 and LTC7000-1 variants, including LTC7000EMSE#PBF and LTC7000JMSE-1#PBF. However, functional differences exist: the "MP" grade adds extended temperature support, and the absence of "-1" denotes inclusion of RUN, OVLO, ISET, and IMON pins - verified in the Pin Configuration and Order Information tables.
