Product details
Overview
LTC7000JMSE-1#WPBF from Analog Devices is a high-voltage, fast-turning high-side N-channel MOSFET gate driver IC designed for static and switching power control applications. It operates from 3.5V to 135V input, delivers 1Ω pull-down / 2.2Ω pull-up drive strength, achieves 35ns propagation delay, and integrates an internal charge pump enabling 100% duty cycle operation - used in industrial load switches, electronic valves, and high-frequency high-side gate drive circuits.
For engineers reviewing the LTC7000JMSE-1#WPBF datasheet, LTC7000JMSE-1#WPBF pinout, LTC7000JMSE-1#WPBF application, or LTC7000JMSE-1#WPBF equivalent, key selection criteria include its 135V max VIN rating, adjustable overcurrent trip threshold (30mV ΔVTH default), open-drain FAULT flag, thermally enhanced 16-lead MSOP package with exposed GND pad, and automotive-grade temperature range (–40°C to 150°C).
Technical Context
The LTC7000JMSE-1#WPBF implements a level-shifted, high-side gate driver architecture with integrated charge pump that regulates BST–TS to 12V, enabling continuous conduction of external N-MOSFETs up to 150V drain-source potential. Its current-sense comparator monitors ΔVSNS across an external sense resistor and triggers fault shutdown after programmable timer delay.
Unlike the LTC7000 variant, the LTC7000-1 family (including LTC7000JMSE-1#WPBF) omits RUN, OVLO, ISET, and IMON pins - simplifying configuration while retaining core protection: overcurrent detection, automatic retry with cooldown, and open-drain FAULT assertion. The device enters active mode when VIN exceeds 3.5V and requires no external enable signal.
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 - enables precise timing control in high-frequency switching and fast transient response systems. |
| Driver Strength | 1Ω pull-down / 2.2Ω pull-up - ensures rapid MOSFET turn-on/turn-off, minimizing switching losses. |
| Charge Pump Output | Regulated 12V BST–TS - sustains 100% duty cycle gate drive for N-MOSFETs without bootstrap diode or capacitor decay. |
| Overcurrent Trip | 30mV ΔVTH (fixed, no ISET pin) - sets low-loss current sensing with minimal sense resistor power dissipation. |
| Package | 16-lead MSOP with exposed thermal pad - provides 10°C/W junction-to-case thermal resistance for high-power reliability. |
| Operating Temp | –40°C to 150°C - qualified for under-hood automotive and high-temp industrial environments. |
Pinout & Package
Package: 16-lead plastic MSOP (MSE16), thermally enhanced with exposed GND pad (Pin 17). Pin spacing optimized for 135V isolation; creepage/clearance compliant per high-voltage safety requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 2) | Main high-voltage supply input | Accepts 3.5V–135V DC; powers internal LDO and charge pump; bypass with ≥0.1µF ceramic to GND. |
| VCC (Pin 3) | Internal LDO output & driver supply | 10V regulated output (or follows VIN if <10V); powers logic and gate drivers; decouple with ≥1µF ceramic. |
| FAULT (Pin 5) | Open-drain fault indicator | Pulls low during overcurrent fault; 200Ω typical pull-down; requires external pull-up for logic-level signaling. |
| TIMER (Pin 6) | Fault timing capacitor node | Connects to GND via CT to set fault warning, shutdown, and auto-retry intervals; disables timer if >3.5V. |
| INP (Pin 7) | CMOS-compatible enable input | Active-high control: drives TGUP/TGDN when >1.7V; internal 1MΩ pull-down holds TGDN low at startup. |
| TGDN (Pin 11) | High-current gate pull-down terminal | Directly connects to MOSFET gate; pulls to TS (high-side source) to turn off; 1Ω on-resistance. |
| TGUP (Pin 12) | High-current gate pull-up terminal | Connects to BST; drives gate high relative to TS; 2.2Ω on-resistance; tie to TGDN for fastest edge rates. |
| TS (Pin 13) | High-side source reference | Return path for high-side load; connects to MOSFET source; serves as local ground for gate drive loop. |
| BST (Pin 14) | Bootstrapped supply rail | Swings between ~12V and (VIN + 12V); supplies TGUP; bypass with ≥0.1µF ceramic to TS. |
| SNS+ (Pin 16) | Current sense positive input | Kelvin-connected to sense resistor high side; monitors ΔVSNS for overcurrent detection. |
| SNS– (Pin 15) | Current sense negative input | Connected to sense resistor low side via ≥100Ω resistor; forms differential pair with SNS+. |
| GND (Pin 17) | Exposed thermal pad / system ground | Mandatory PCB solder connection for thermal management and electrical reference; ties internally to all GND nodes. |
Key Features
| Feature | Design Value |
|---|---|
| 100% Duty Cycle Support | Integrated charge pump maintains stable 12V BST–TS rail independent of switching frequency or duty cycle. |
| Fast Fault Response | 70ns overcurrent-to-TGDN-low propagation delay ensures rapid MOSFET shutdown before thermal damage. |
| Automated Retry Logic | Programmable cooldown period followed by automatic restart eliminates need for external reset circuitry. |
| High-Voltage Isolation | MSOP package with 0.657mm pin spacing meets reinforced insulation requirements for 135V operation. |
| Low Quiescent Current | 1µA shutdown current (when INP = 0V) minimizes standby power in always-on systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5109BMAX/NOPB | Lower max VIN (65V), no integrated charge pump, requires external bootstrap diode/capacitor, no overcurrent protection. | Suitable only for ≤65V systems without current monitoring; lacks auto-retry and FAULT flag. | Select when cost sensitivity outweighs protection features and voltage headroom is sufficient. |
| UCC27531DR | Max VIN = 24V, no high-side level shift, no charge pump, no overcurrent detection - purely a low-side/high-side dual driver. | Requires external high-side level shifter and current sense circuit; not a drop-in replacement for 135V applications. | Choose only for low-voltage (<24V), non-protected gate driving where board space is constrained. |
Compared with LM5109BMAX/NOPB and UCC27531DR, the LTC7000JMSE-1#WPBF uniquely combines 135V operation, integrated charge pump, fixed 30mV overcurrent threshold, and automotive-grade thermal rating - making it the only option among the three capable of standalone high-voltage static switching with embedded protection.

FAQ
What is the maximum input voltage rating for the LTC7000JMSE-1#WPBF?
The LTC7000JMSE-1#WPBF has an absolute maximum VIN rating of 150V and a recommended operating range of 3.5V to 135V. This allows safe integration into 48V, 60V, and 110V industrial and automotive power systems while maintaining margin against transients. Exceeding 135V during normal operation risks violating SOA limits even if below the 150V absolute maximum.
Does the LTC7000JMSE-1#WPBF support 100% duty cycle operation?
Yes, the LTC7000JMSE-1#WPBF supports true 100% duty cycle operation via its integrated charge pump, which maintains a regulated 12V BST–TS voltage regardless of switching frequency or on-time duration. This eliminates bootstrap capacitor discharge issues common in traditional high-side drivers and enables continuous conduction in static switch applications.
How does overcurrent protection work in the LTC7000JMSE-1#WPBF?
The LTC7000JMSE-1#WPBF detects overcurrent by measuring the voltage difference (ΔVSNS) across an external sense resistor connected between SNS+ and SNS–. When ΔVSNS exceeds the fixed 30mV threshold, a fault timer begins; upon timeout, TGDN is pulled to TS to turn off the MOSFET. The FAULT pin asserts low, and after a cooldown period, the device automatically retries.
What is the purpose of the TIMER pin on the LTC7000JMSE-1#WPBF?
The TIMER pin on the LTC7000JMSE-1#WPBF accepts an external capacitor to GND that sets three time intervals: fault warning delay (before FAULT asserts), fault shutdown delay (before TGDN pulls low), and auto-retry cooldown period. Connecting TIMER to >3.5V disables timing and forces immediate TGDN pull-down on overcurrent detection - useful for critical fail-fast scenarios.
Is the LTC7000JMSE-1#WPBF pin-compatible with the LTC7000JMSE#WPBF?
No, the LTC7000JMSE-1#WPBF is not pin-compatible with the LTC7000JMSE#WPBF. The -1 suffix denotes the absence of RUN, OVLO, ISET, and IMON pins - reducing pin count and simplifying layout but removing adjustable UVLO/OVLO, current threshold programming, and current monitor functionality. Pin mapping differs significantly between the two variants.
