Product details
Overview
LTC7001IMSE#PBF from Analog Devices is a fast 150V high-side N-channel MOSFET gate driver IC with internal charge pump, enabling 100% duty cycle operation. It operates from input voltages up to 135V (150V abs max), features 1Ω pull-down and 2.2Ω pull-up drivers, and delivers 35ns propagation delay into 1nF load - ideal for static switch, electronic valve, and high-frequency high-side gate drive applications in industrial power systems.
For engineers reviewing the LTC7001IMSE#PBF datasheet, LTC7001IMSE#PBF pinout, LTC7001IMSE#PBF application, or LTC7001IMSE#PBF equivalent, key selection criteria include its 135V VIN range, adjustable VCC undervoltage lockout via VCCUV pin, OVLO threshold programmability, BST-TS floating UVLO at 3.1V, and thermally enhanced 10-lead MSOP package with exposed GND pad.
Technical Context
The LTC7001IMSE#PBF integrates a high-voltage level shifter and internal charge pump that regulates BST–TS to 12V, enabling indefinite conduction of external high-side NMOS switches. Its dual-output architecture separates TGUP (pull-up to BST) and TGDN (pull-down to TS) for independent slew control and fast transient immunity.
CMOS-compatible INP input includes 1MΩ internal pull-down and 400mV hysteresis (VIH = 2.0V, VIL = 1.6V), ensuring noise-immune logic control. Protection circuitry includes VCCUV-configurable undervoltage lockout, OVLO-triggered shutdown, BST–TS floating UVLO, and thermal shutdown at ~180°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 0V to 135V - supports direct connection to high-voltage DC bus up to 150V absolute max. |
| Driver Output Resistance | TGUP: 2.2Ω typ, TGDN: 1Ω typ - enables fast switching of large gate capacitances with minimal transition loss. |
| Propagation Delay | 35ns typ (INP to TG output, CL = 1nF) - ensures precise timing control in high-frequency gate drive loops. |
| Charge Pump Output | Regulates BST–TS to 12V - sustains 100% duty cycle without external bootstrap diode or capacitor recharge limitations. |
| VCC Supply Range | 3.5V to 15V - powers internal logic and gate driver stages; UVLO threshold adjustable from 3.5V to 10.5V via VCCUV pin. |
| OVLO Threshold | 1.16V (rising), 1.05V (falling) - sets precise input overvoltage lockout using external resistor divider on OVLO pin. |
| Operating Temp | –40°C to +125°C junction - qualified for industrial and automotive-grade reliability per AEC-Q100 (I-grade). |
Pinout & Package
Package: 10-lead plastic MSOP (MSE) with exposed thermal pad (Pin 11 = GND), θJA = 45°C/W, θJC = 10°C/W. Exposed pad must be soldered to PCB ground plane for rated thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (1) | Main logic supply input | Accepts 3.5V–15V; bypass with ≥0.1µF capacitor to GND; powers internal regulators and logic. |
| VCCUV (2) | VCC undervoltage lockout reference | Resistor-to-GND sets rising VCC UVLO from 3.5V to 10.5V; open = 7.0V default. |
| GND (3, 11) | Ground reference & thermal path | Pin 3 and exposed pad (11) are internally connected; pad must be soldered to PCB GND plane. |
| INP (4) | CMOS-compatible enable input | Active-high logic input with 1MΩ internal pull-down; VIH = 2.0V, VIL = 1.6V, 400mV hysteresis. |
| OVLO (5) | Input overvoltage detection input | Resistor divider from VIN sets lockout threshold; >1.21V pulls TGDN to TS and disables output. |
| TGDN (6) | High-current pull-down output | Drives external MOSFET gate to TS (high-side source); 1Ω RDS(ON) enables fast turn-off. |
| TGUP (7) | High-current pull-up output | Drives external MOSFET gate to BST (bootstrapped supply); 2.2Ω RDS(ON); optional series resistor for slew control. |
| TS (8) | High-side source reference | Connects to source of external high-side NMOS; tolerant to –6V to +150V; serves as local ground for driver stage. |
| BST (9) | Bootstrapped supply output | Internal charge pump maintains BST–TS ≈ 12V; requires ≥0.1µF capacitor to TS for stable gate drive voltage. |
| NC (10) | No-connect terminal | Must be left floating; no internal connection or function. |
Key Features
| Feature | Design Value |
|---|---|
| 100% duty cycle capability | Internal charge pump sustains BST–TS at 12V indefinitely, eliminating need for external bootstrap diode or duty-cycle limitation. |

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 | Fixed 12V gate drive, no internal charge pump; requires external bootstrap diode; max VIN = 100V; no OVLO/VCCUV adjustment. | Suitable only for <100V applications with fixed 12V gate drive; lacks programmable protection and 100% duty cycle support. | Select when cost sensitivity outweighs programmability and 135V+ operation; verify external bootstrap design for duty cycle requirements. |
| MAX15062AATA+ | Integrated high-side switch (not driver-only); 60V max; built-in current sense and fault reporting; no BST pin or external MOSFET flexibility. | Targeted at lower-voltage, integrated load-switch applications; not suitable for discrete high-voltage NMOS gate drive. | Choose only for ≤60V embedded load-switch designs requiring integrated protection telemetry; not a functional substitute for LTC7001IMSE#PBF. |
Compared with LM5109BMM/NOPB and MAX15062AATA+, the LTC7001IMSE#PBF uniquely combines 135V input capability, internal charge pump for true 100% duty cycle, and fully programmable OVLO/VCCUV thresholds - making it the only option among the three capable of robust, flexible high-voltage static switching in industrial and automotive environments.

FAQ
What is the maximum input voltage rating for the LTC7001IMSE#PBF?
The LTC7001IMSE#PBF has an absolute maximum TS pin voltage of 150V and a specified operating VIN range of 0V to 135V. This allows direct interface with high-voltage DC buses such as 48V, 60V, and 100V industrial systems while maintaining safe margin below the 150V absolute limit. Operation beyond 135V violates the guaranteed specification and may impair reliability.
How does the internal charge pump in the LTC7001IMSE#PBF enable 100% duty cycle operation?
The LTC7001IMSE#PBF uses an internal charge pump to regulate the BST–TS voltage to approximately 12V regardless of duty cycle. Unlike bootstrap circuits dependent on periodic low-side conduction, this charge pump draws current from either VCC or TS to maintain BST–TS, allowing the external high-side NMOS to remain fully enhanced indefinitely - a critical capability for static switch and electronic breaker applications.
Can the LTC7001IMSE#PBF drive a MOSFET with gate charge (QG) exceeding 100nC?
Yes - the LTC7001IMSE#PBF's 1Ω pull-down and 2.2Ω pull-up drivers deliver sufficient peak current to drive high-QG MOSFETs. For example, with a 12V gate drive swing, the peak current exceeds 5A into low-impedance gates. However, the external bootstrap capacitor (CB) must be sized per CB > QG / 1V; for QG = 100nC, CB ≥ 0.1µF is required, matching the recommended minimum value.
What is the purpose of the NC pin (Pin 10) on the LTC7001IMSE#PBF?
Pin 10 of the LTC7001IMSE#PBF is designated NC (No Connect) and has no internal connection or electrical function. It must be left unconnected (floating) on the PCB layout. Soldering or routing to this pin may cause mechanical stress or unintended coupling and is strictly prohibited per the datasheet.
Does the LTC7001IMSE#PBF support adjustable turn-off time?
No - the LTC7001IMSE#PBF provides fixed-fast turn-off via the low-impedance 1Ω TGDN pull-down path directly to TS. Turn-on slew rate is adjustable using an external resistor between TGUP and the MOSFET gate, but turn-off remains inherently fast and unmodified. This asymmetry ensures reliable, rapid fault clearing while allowing controlled inrush management during startup.
