Product details
Overview
LTC7000HMSE#PBF from Analog Devices is a high-voltage, fast-turning high-side N-channel MOSFET gate driver IC designed for static and high-frequency switching applications up to 135V input. It features 35ns propagation delay, 1Ω pull-down / 2.2Ω pull-up gate drive strength, internal charge pump enabling 100% duty cycle operation, adjustable overcurrent protection via ISET pin, and operates across –40°C to +150°C junction temperature range.
For engineers reviewing the LTC7000HMSE#PBF datasheet, LTC7000HMSE#PBF pinout, LTC7000HMSE#PBF application, or LTC7000HMSE#PBF equivalent, this page delivers verified technical context, real-world design meaning of key specs, validated pin functions, application-specific implementation guidance, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The LTC7000HMSE#PBF implements a level-shifted CMOS-compatible input stage driving high-side NMOS switches with bootstrapped gate supply (BST–TS), where internal charge pump regulation maintains 12V BST–TS across 3.5V–135V VIN. Its current-sense comparator monitors ΔVSNS across an external sense resistor, triggering fault shutdown after programmable timer delay when ΔVTH (20–75mV, set by ISET) is exceeded.
Protection logic includes open-drain FAULT flag assertion at 1.3V TIMER threshold, automatic retry after cooldown, VCC undervoltage lockout (adjustable via VCCUV pin), and RUN/OVLO inputs for precise input supply UVLO/OVLO control - all operating with thermal shutdown at ~180°C and guaranteed startup below 150°C.
Key Specifications

Pinout & Package
Package: 16-lead plastic MSOP (MSE16) with exposed GND pad (Pin 17), thermally enhanced for high-power dissipation; rated for 150°C max junction temperature and 45°C/W θJA.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RUN (1) | Enable/UVLO Control Input | Enables operation above 1.21V; shuts down to 1µA at <0.7V - used for system-level power sequencing and input rail monitoring. |
| VIN (2) | Main High-Voltage Supply Input | Accepts 3.5V–135V; powers internal LDO and charge pump - requires ≥0.1µF ceramic bypass to GND. |
| VCC (3) | Internal LDO Output / Gate Driver Supply | 10V regulated output (or follows VIN if <10V); powers logic and drivers - must be decoupled with ≥1µF low-ESR capacitor. |
| VCCUV (4) | VCC Undervoltage Lockout Reference | Sets gate-drive UVLO threshold (×7 multiplier); short to GND = 3.5V UVLO, open = 7.0V UVLO. |
| FAULT (5) | Open-Drain Fault Flag Output | Pulls low when TIMER reaches 1.3V - signals imminent overcurrent shutdown; 200Ω typical pull-down impedance. |
| TIMER (6) | Fault Timing Capacitor Node | CT-to-GND sets warning, shutdown, and auto-retry intervals - connect to VCC for immediate fault response. |
| INP (7) | CMOS-Compatible Control Input | Active-high logic input referenced to GND; internal 1MΩ pull-down ensures safe default-off state. |
| OVLO (8) | Input Overvoltage Lockout Input | Triggers fault when voltage exceeds 1.21V - used with resistive divider to protect against input surges. |
| ISET (9) | Adjustable Current Trip Threshold | Sets ΔVTH = VISET/20 (20–75mV); grounded = 20mV min, open = 30mV typical - enables loss optimization. |
| IMON (10) | Current Monitor Output | Ground-referenced 0–1.5V output = 20×ΔVSNS - provides isolated current feedback for diagnostics or closed-loop control. |
| TGDN (11) | High-Current Gate Pull-Down | Direct TS-referenced sink - connects to MOSFET gate for fastest turn-off; low 1Ω RON minimizes tf. |
| TGUP (12) | High-Current Gate Pull-Up | Bootstrap-referenced source (to BST) - drives gate high; series resistor controls dV/dt during turn-on. |
| TS (13) | Top-Side Source Reference | High-side return path - connects to MOSFET source; can be tied to GND in low-side configurations. |
| BST (14) | Bootstrap Supply Rail | Swings from 12V to (VIN+12V); requires ≥0.1µF capacitor to TS - enables high-side NMOS drive without external supply. |
| SNS– (15) | Negative Current Sense Input | Kelvin-connected to sense resistor low side - 100Ω series resistor suppresses noise and ESD transients. |
| SNS+ (16) | Positive Current Sense Input | Kelvin-connected to sense resistor high side - differential pair with SNS– forms precision current comparator input. |
| GND (17) | Exposed Thermal Pad / Ground | Mandatory PCB solder connection - provides primary thermal path and electrical ground reference for all circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side NMOS gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5109BMM/NOPB | No integrated charge pump; requires external bootstrap diode/capacitor; fixed 1.5A peak drive; no current monitor or ISET adjustment. | Lacks programmable overcurrent protection and IMON feedback - suitable only for simpler on/off switching without diagnostics. | Select when cost sensitivity outweighs diagnostic capability and 100% duty cycle requirement is not needed. |
| UCC27531DR | Lower voltage rating (120V abs max); no internal LDO or charge pump; no OVLO/RUN pins; no TIMER-based fault management. | Designed for mid-voltage DC-DC gate driving - lacks the protection architecture and high-temp qualification required for automotive or industrial mains-connected loads. | Choose for compact, high-speed gate driving below 100V where external bias supplies and discrete protection are acceptable. |

FAQ
What is the maximum input voltage rating for the LTC7000HMSE#PBF?
The LTC7000HMSE#PBF has an absolute maximum VIN rating of 150V and a specified operating range of 3.5V to 135V. This makes it suitable for 100V-class industrial and automotive power systems where transient tolerance and sustained high-voltage operation are required. The device maintains full functionality and protection features across this entire range, including charge pump regulation and overcurrent detection.
Does the LTC7000HMSE#PBF support 100% duty cycle operation, and how is it achieved?
Yes, the LTC7000HMSE#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 duty cycle. This eliminates reliance on external bootstrap diodes and capacitors, enabling continuous conduction in static switch and PWM applications - a key differentiator from non-pump gate drivers like UCC27531DR.
How does the ISET pin adjust overcurrent protection on the LTC7000HMSE#PBF?
The ISET pin on the LTC7000HMSE#PBF sets the current sense threshold voltage (ΔVTH) as VISET/20, ranging from 20mV (ISET grounded) to 75mV (ISET at 1.5V). With ISET open, ΔVTH defaults to 30mV - enabling accurate, low-loss current sensing using sub-10mΩ shunt resistors. This direct analog programming avoids digital configuration overhead and supports real-time analog loop integration.
What is the purpose of the IMON pin, and is it available on all LTC7000 variants?
The IMON pin on the LTC7000HMSE#PBF provides a ground-referenced 0–1.5V analog output equal to 20× the voltage across the external sense resistor (ΔVSNS), enabling real-time current monitoring without additional signal conditioning. This feature is exclusive to the LTC7000 (non-"-1") variants - the LTC7000-1 family omits IMON and ISET pins, offering simplified protection-only operation.
What thermal specifications distinguish the LTC7000HMSE#PBF from standard-grade versions?
The LTC7000HMSE#PBF is rated for –40°C to +150°C junction temperature operation and is qualified per AEC-Q100 for automotive use. Its exposed-pad MSOP package achieves θJA = 45°C/W and includes thermal shutdown at ~180°C. In contrast, standard E-grade versions (e.g., LTC7000EMSE#PBF) are only guaranteed to 125°C - making the H-grade essential for under-hood, high-ambient, or high-power-density deployments.
