Product details
Overview
LTC7001EMSE#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 and automotive power systems.
For engineers reviewing the LTC7001EMSE#PBF datasheet, LTC7001EMSE#PBF pinout, LTC7001EMSE#PBF application, or LTC7001EMSE#PBF equivalent, key selection criteria include its 135V VIN range, adjustable VCC undervoltage lockout (3.5–10.5V), programmable OVLO threshold, gate slew rate control, and thermally enhanced 10-lead MSOP package rated for –40°C to 125°C junction temperature.
Technical Context
The LTC7001EMSE#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 without bootstrap capacitor recharge limitations. Its dual-output architecture separates TGUP (pull-up to BST) and TGDN (pull-down to TS) for independent turn-on/turn-off control.
Protection logic includes three independent undervoltage lockouts: VCCUV-configurable VCC UVLO (3.5–10.5V), OVLO-pin-based input overvoltage lockout (1.11–1.21V threshold), and BST–TS floating UVLO (3.1V typical). All lockouts force TGDN to TS, ensuring fail-safe shutdown under fault conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 0V to 135V continuous; supports 150V absolute max - enables direct interface with high-voltage DC bus systems. |
| Driver Output Resistance | TGUP: 2.2Ω typ; TGDN: 1Ω typ - ensures fast switching into large gate capacitances (e.g., >1nF) with minimal transition loss. |
| Propagation Delay | 35ns typ (INP to TG output, CL = 1nF) - supports high-frequency PWM and precise timing-critical static switching. |
| Charge Pump Output | Regulates BST–TS to 12V with ±1V tolerance - sustains 100% duty cycle without external bootstrap diode or capacitor recharge circuitry. |
| Input Thresholds | VIH = 2.0V, VIL = 1.6V, 400mV hysteresis - provides noise-immune CMOS-compatible logic interface independent of VCC variation. |
| Operating Temp | –40°C to +125°C junction - qualified per AEC-Q100 Grade E, suitable for under-hood automotive and industrial environments. |
| VCC Supply Range | 3.5V to 15V - allows flexible biasing from auxiliary rails or isolated supplies while maintaining full gate drive capability. |
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 (Pin 1) | Main logic supply input | Bypass with ≥0.1µF to GND; powers internal logic, charge pump controller, and input buffer. |
| VCCUV (Pin 2) | VCC undervoltage lockout reference | Resistor-to-GND sets rising VCC UVLO threshold from 3.5V to 10.5V; open = 7.0V default. |
| GND (Pin 3 & Pin 11) | Signal and thermal ground | Pin 3 = signal GND; Pin 11 = exposed pad = GND - mandatory solder connection for thermal management. |
| INP (Pin 4) | CMOS-compatible enable input | Active-high logic input with 1MΩ internal pull-down; controls TGUP/TGDN state; tolerant to –6V to +15V transients. |
| OVLO (Pin 5) | Input overvoltage detection input | Resistive divider from VIN sets lockout at 1.11–1.21V; >1.21V forces TGDN to TS, disabling external MOSFET. |
| TGDN (Pin 6) | High-current gate pull-down output | Drives external MOSFET gate to TS (high-side source); 1Ω RDS(ON) enables rapid turn-off. |
| TGUP (Pin 7) | High-current gate pull-up output | Drives external MOSFET gate to BST (bootstrapped supply); 2.2Ω RDS(ON); series resistor optional for slew control. |
| TS (Pin 8) | High-side source reference | Connects to external MOSFET source; serves as local ground reference for level-shifted outputs; rated –6V to +150V. |
| BST (Pin 9) | Bootstrapped supply output | Connects via ≥0.1µF capacitor to TS; voltage = VTS + 12V; supplies gate drive for high-side NMOS. |
| NC (Pin 10) | No-connect terminal | Must remain unconnected; no internal connection or function. |
Key Features
| Feature | Design Value |
|---|---|
| 100% duty cycle support | Internal charge pump maintains BST–TS at 12V regardless of TS voltage - eliminates need for external bootstrap diode or duty-cycle limitation. |
| Adjustable turn-on slew rate | Series resistor between TGUP and MOSFET gate controls dV/dt during turn-on - reduces EMI and inrush current in capacitive loads. |
| Triple fault protection | Independent VCC UVLO, OVLO, and BST–TS UVLO circuits all force TGDN to TS - ensures safe shutdown under supply, input, or bootstrap faults. |
| AEC-Q100 qualification | Qualified for automotive Grade E (–40°C to +125°C) - validated for reliability in engine control, battery disconnect, and ADAS power management. |
| High dv/dt immunity | Level-shifter design tolerates >50V/ns transients on TS pin - maintains stable gate drive during fast-switching inductive load commutation. |

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 | Lower VIN max (65V), no internal charge pump (requires external bootstrap diode), fixed 5V VDD UVLO. | Suitable only for ≤65V systems; cannot support true 100% duty cycle without external components. | Select when cost sensitivity outweighs high-voltage capability and simplicity; requires additional BOM and layout area. |
| MAX15062AATA+ | Higher VIN max (200V), but no adjustable OVLO/VCCUV; fixed 3.3V/5V logic interface; no AEC-Q100 qualification. | Targeted at telecom/datacom, not automotive; lacks programmable protection thresholds critical for industrial safety compliance. | Prefer for ultra-high-voltage non-automotive applications where fixed thresholds suffice and qualification is not required. |
Compared with LM5109BMM/NOPB and MAX15062AATA+, the LTC7001EMSE#PBF uniquely combines 135V operation, internal charge pump for 100% duty cycle, dual-programmable UVLO/OVLO, and AEC-Q100 qualification - making it the only single-chip solution for robust, high-reliability high-side switching in demanding automotive and industrial environments.

FAQ
What is the maximum continuous input voltage supported by the LTC7001EMSE#PBF?
The LTC7001EMSE#PBF supports continuous input voltages up to 135V on the TS pin, with an absolute maximum rating of 150V. This enables direct use in 48V, 60V, and 100V industrial and automotive DC bus applications without external voltage scaling or clamping circuitry. Operation above 135V violates the recommended operating conditions and may compromise reliability.
Does the LTC7001EMSE#PBF require an external bootstrap diode?
No, the LTC7001EMSE#PBF does not require an external bootstrap diode. Its integrated charge pump actively regulates the BST–TS voltage to 12V, enabling true 100% duty cycle operation. An external silicon diode between VCC and BST is optional - only needed if power-up time or high-frequency switching (>500Hz) causes BST–TS collapse, per the datasheet's design equations.
How is the VCC undervoltage lockout threshold set on the LTC7001EMSE#PBF?
The VCC undervoltage lockout (UVLO) threshold on the LTC7001EMSE#PBF is set by connecting a resistor between VCCUV (Pin 2) and GND. The internal 10µA current source generates a voltage at VCCUV, which is multiplied by seven to determine the rising UVLO threshold. With VCCUV open, the threshold defaults to 7.0V; a 100kΩ resistor sets it to ~3.5V, and values from 50kΩ to 150kΩ yield thresholds from ~3.5V to ~10.5V.
Can the LTC7001EMSE#PBF drive a MOSFET with gate charge exceeding 100nC?
Yes, the LTC7001EMSE#PBF can drive MOSFETs with gate charge exceeding 100nC. Its 1Ω pull-down and 2.2Ω pull-up drivers deliver high peak current, and the 12V gate drive voltage reduces RDS(ON) losses. For very large QG, ensure the external bootstrap capacitor CB > QG / 1V (e.g., ≥0.1µF for QG = 100nC), and verify thermal performance using θJA = 45°C/W with proper PCB copper area.
Is the LTC7001EMSE#PBF pin-compatible with other variants in the LTC7001 family?
Yes, the LTC7001EMSE#PBF is pin-compatible with all other LTC7001 variants in the 10-lead MSOP package (e.g., LTC7001IMSE#PBF, LTC7001JMSE#PBF), sharing identical pinout, footprint, and electrical interface. Differences lie solely in temperature grade (E = –40°C to +125°C), qualification (AEC-Q100 for E-grade), and guaranteed performance limits - allowing drop-in substitution where thermal and reliability requirements align.
