Product details
Overview
LTC7000HMSE-1#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 external timing capacitor, and operates across –40°C to +150°C junction temperature range.
For engineers reviewing the LTC7000HMSE-1#PBF datasheet, LTC7000HMSE-1#PBF pinout, LTC7000HMSE-1#PBF application, or LTC7000HMSE-1#PBF equivalent, key selection considerations include high-side gate drive capability at 135V VIN, fast fault response with programmable retry timer, thermal robustness for automotive and industrial environments, and compatibility with discrete N-channel MOSFETs requiring bootstrap-enhanced gate voltage.
Technical Context
The LTC7000HMSE-1#PBF implements a level-shifted CMOS-compatible input stage driving dual high-current output stages (TGUP/TGDN) referenced to TS (high-side source). Its integrated charge pump maintains BST–TS at ~12V independent of VIN, enabling full enhancement of external N-MOSFETs even at low VCC or high VIN.
Overcurrent detection uses a precision current-sense comparator monitoring ΔVSNS across an external shunt, with trip threshold ΔVTH fixed at 30mV (ISET open), triggering fault flag assertion and TGDN pull-down after programmable delay set by CTIMER. Automatic restart occurs post-cooldown without external intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 3.5V to 135V - supports wide-input industrial and automotive power rails without external regulation |
| Propagation Delay | 35ns - enables precise timing control in high-frequency switching or fast transient load switching |
| TG Pull-Down Resistance | 1Ω - ensures rapid MOSFET turn-off under high dV/dt conditions and inductive loads |
| TG Pull-Up Resistance | 2.2Ω - balances fast turn-on speed against gate ringing and EMI in high-side configurations |
| Operating Temp Range | –40°C to +150°C - qualified for under-hood automotive and harsh-environment industrial use |
| Charge Pump Output | 12V BST–TS - sustains 100% duty cycle gate drive without external bootstrap diode/capacitor complexity |
| Fault Response Time | 70ns overcurrent-to-TGDN-low - provides sub-100ns protection against short-circuit events |
Pinout & Package
The LTC7000HMSE-1#PBF is housed in a thermally enhanced 16-lead MSOP package (MSE16) with exposed GND pad (Pin 17) requiring PCB soldering for thermal and electrical performance. High-voltage creepage is optimized per MSE16(12) variant specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 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 | Regulated 10V output (or follows VIN below dropout); powers logic and gate drivers; decouple with ≥1µF ceramic |
| INP (Pin 7) | CMOS-compatible enable input | GND-referenced digital control signal; internal 1MΩ pull-down holds TGDN low during startup |
| TGUP (Pin 12) | High-side gate pull-up driver | Drives external MOSFET gate to BST potential; connects directly to gate or via series resistor for slew control |
| TGDN (Pin 11) | High-side gate pull-down driver | Pulls MOSFET gate to TS (source) during fault or INP low; low 1Ω impedance ensures fast turn-off |
| SNS+ / SNS– (Pins 16/15) | Differential current sense inputs | Monitor voltage across external shunt; Kelvin connection recommended; ΔVTH = 30mV (ISET open) |
| FAULT (Pin 5) | Open-drain fault indicator | Pulls low when overcurrent detected; typical 200Ω pull-down; remains asserted until cooldown and reset |
| TS (Pin 13) | High-side source reference | Connects to MOSFET source; serves as local ground reference for TGUP/TGDN and sense circuitry |
Key Features
| Feature | Design Value |
|---|---|
| 100% Duty Cycle Support | Integrated charge pump maintains stable 12V BST–TS rail regardless of VIN or switching frequency |
| Fast Fault Protection | 70ns overcurrent-to-TGDN-low propagation ensures MOSFET survival during hard shorts |
| Thermal Robustness | Rated for continuous operation up to +150°C junction temperature; exposed pad mandatory for spec compliance |
| Programmable Retry Timer | External CTIMER capacitor sets fault warning, shutdown, and automatic restart intervals independently |
| High-Voltage Pin Spacing | MSE16(12) package variant provides 0.657mm creepage for reliable 135V operation in compact layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side N-MOSFET gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5109BMM/NOPB | Lower max VIN (65V), no integrated charge pump, no overcurrent protection, 105°C max temp | Suitable only for ≤65V non-fault-protected static switches; lacks current sensing and auto-retry | Select when cost sensitivity outweighs fault protection and high-voltage capability |
| UCC27531DR | 60V max VIN, no charge pump, no current sense, no fault flag, 125°C max temp | Designed for low-side or bootstrapped high-side use with external floating supply; no built-in protection logic | Choose for simple gate drive where external protection and thermal margin are managed separately |
Compared with LM5109BMM/NOPB and UCC27531DR, the LTC7000HMSE-1#PBF uniquely integrates 135V operation, self-contained charge pump, differential current sensing, programmable fault timing, and AEC-Q100-rated 150°C operation-making it the only option for robust, single-chip high-side protection in automotive and industrial 48V–135V systems.

FAQ
What is the maximum input voltage rating for the LTC7000HMSE-1#PBF?
The LTC7000HMSE-1#PBF has an absolute maximum VIN rating of 150V and a specified operating range of 3.5V to 135V. This allows direct interface with 48V, 60V, and 96V industrial and automotive DC buses while maintaining safe margin against transients. Operation beyond 135V violates the functional specification and may trigger undervoltage lockout or damage the device.
Does the LTC7000HMSE-1#PBF include overcurrent protection, and how is it configured?
Yes, the LTC7000HMSE-1#PBF includes integrated overcurrent protection using differential sense inputs (SNS+/SNS–) and a fixed 30mV trip threshold (ISET open). When ΔVSNS exceeds this threshold, the FAULT pin asserts and TGDN pulls low after a delay set by the external CTIMER capacitor. No resistor on ISET is required for basic operation, simplifying design for standard current-limit applications.
How does the LTC7000HMSE-1#PBF achieve 100% duty cycle operation without an external bootstrap diode?
The LTC7000HMSE-1#PBF achieves 100% duty cycle operation via an internal charge pump that regulates the BST–TS voltage to ~12V. Unlike traditional bootstrap circuits limited by duty cycle and frequency, this charge pump draws from either TS or VCC, sustaining gate drive voltage indefinitely-even at DC-eliminating need for external diodes, capacitors, or timing constraints.
What is the operating temperature range of the LTC7000HMSE-1#PBF, and is it AEC-Q100 qualified?
The LTC7000HMSE-1#PBF is rated for continuous operation from –40°C to +150°C junction temperature and is AEC-Q100 qualified for automotive applications. This qualification covers stress testing for temperature cycling, humidity, ESD, and latch-up-ensuring reliability in under-hood environments where ambient temperatures exceed 105°C and thermal gradients are severe.
Can the LTC7000HMSE-1#PBF drive SiC or GaN MOSFETs, and what gate drive strengths does it provide?
Yes, the LTC7000HMSE-1#PBF can drive SiC and GaN N-MOSFETs thanks to its 2.2Ω pull-up and 1Ω pull-down output impedances, 35ns propagation delay, and 12V BST–TS gate supply. These characteristics minimize switching losses and support fast transitions required by wide-bandgap devices-especially critical in high-frequency (>300kHz) topologies where gate charge and Miller capacitance demand strong, low-impedance drive.
