Product details
Overview
LTC7001EMSE#TRPBF 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, 35ns propagation delay, and supports gate driver supply from 3.5V to 15V. It is used in high-voltage static switch and load-switch applications requiring fast, robust high-side control.
For engineers reviewing the LTC7001EMSE#TRPBF datasheet, LTC7001EMSE#TRPBF pinout, LTC7001EMSE#TRPBF application, or LTC7001EMSE#TRPBF equivalent, key selection considerations include its 135V VIN capability, adjustable VCC undervoltage lockout via VCCUV pin, programmable OVLO threshold, internal charge pump for continuous conduction, and thermally enhanced 10-lead MSOP package with exposed GND pad.
Technical Context
The LTC7001EMSE#TRPBF integrates a high-voltage level shifter and charge pump to drive N-channel MOSFETs in high-side configurations where the source (TS) floats up to 135V. Its dual-output architecture separates TGUP (pull-up to BST) and TGDN (pull-down to TS) for independent slew rate control during turn-on and turn-off.
It implements three independent protection comparators: OVLO (adjustable overvoltage lockout on VIN), VCCUV (adjustable VCC undervoltage lockout), and BST-TS floating UVLO (3.1V typical). All protections force TGDN to TS, ensuring fail-safe shutdown of the external MOSFET under fault conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 0V to 135V - supports wide-input industrial and automotive power rails; absolute max 150V. |
| Gate Driver Output Resistance | Pull-up: 2.2Ω typ; Pull-down: 1Ω typ - enables fast switching into large gate capacitances (e.g., 1nF load). |
| Propagation Delay | 35ns typ (INP to TG output) - ensures precise timing control in high-frequency or critical turn-on/turn-off applications. |
| Charge Pump Output | Regulates BST–TS to 12V - sustains 100% duty cycle without external bootstrap diode or capacitor recharge loss. |
| VCC Supply Range | 3.5V to 15V - compatible with standard logic supplies and allows flexible biasing in multi-rail systems. |
| Operating Junction Temp | –40°C to 125°C - specified for extended industrial temperature range (E-grade). |
| Package | 10-Lead Plastic MSOP with exposed thermal pad - θJA = 45°C/W; requires soldered GND pad for thermal and electrical performance. |
Pinout & Package
Package: 10-lead plastic MSOP (MSE), thermally enhanced, with exposed GND pad (Pin 11) that must be soldered to PCB ground plane per datasheet layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Main logic supply input | Accepts 3.5V–15V; powers internal logic and charge pump; requires ≥0.1µF bypass to GND. |
| VCCUV (Pin 2) | VCC undervoltage lockout reference | Resistor-to-GND sets rising/falling UVLO threshold (3.5V–10.5V); open = 7.0V default. |
| GND (Pin 3 + Exposed Pad Pin 11) | Signal and thermal ground reference | Primary return path; exposed pad is electrically GND and mandatory for thermal dissipation. |
| INP (Pin 4) | CMOS-compatible digital input | Active-high control signal; internal 1MΩ pull-down holds TGDN low at startup; VIH = 2.0V, VIL = 1.6V. |
| OVLO (Pin 5) | Input overvoltage lockout sense | Resistive divider from VIN sets lockout threshold (1.11V–1.21V); pulls TGDN to TS when exceeded. |
| TGDN (Pin 6) | High-current gate pull-down output | Drives external MOSFET gate to TS (high-side source); 1Ω RDS(ON) enables fast 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 controls turn-on slew. |
| TS (Pin 8) | High-side source connection | Reference node for high-side MOSFET source; tolerates –6V to 150V; connects to load or VIN rail. |
| BST (Pin 9) | Bootstrapped supply output | Charged by internal pump to VTS + 12V; requires ≥0.1µF capacitor to TS for gate drive energy storage. |
| NC (Pin 10) | No-connect terminal | Must be left floating; 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 and enables continuous conduction. |
| Adjustable turn-on slew rate | Series resistor between TGUP and MOSFET gate controls dV/dt - reduces EMI and inrush current in capacitive loads. |
| Triple independent protection | OVLO, VCCUV, and BST-TS UVLO each independently force TGDN to TS - provides layered fault response for system safety. |
| High-voltage tolerant inputs/outputs | INP withstands –6V to +15V; TS and BST tolerate up to 150V - simplifies interface design in noisy, high-dV/dt environments. |
| Thermally optimized MSOP package | Exposed GND pad + θJC = 10°C/W - enables reliable operation at full 125°C junction temperature with proper PCB layout. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side N-channel 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 if cost-sensitive and VIN ≤65V; avoid for 100V+ or continuous-conduction requirements. |
| MAX5054ASA+ | Higher VIN max (200V), but slower propagation (100ns), no adjustable OVLO/VCCUV, no exposed thermal pad. | Better for ultra-high-voltage transient tolerance; lacks precision protection thresholds and thermal performance of LTC7001EMSE#TRPBF. | Choose for >135V surge margin; accept trade-offs in speed, configurability, and thermal management. |

FAQ
What is the maximum input voltage rating for the LTC7001EMSE#TRPBF?
The LTC7001EMSE#TRPBF has an absolute maximum TS pin voltage of 150V and a recommended operating VIN range of 0V to 135V. Exceeding 150V may cause permanent damage. The device's internal level-shifting architecture and charge pump enable reliable operation across this full range without external high-voltage isolation components.
Does the LTC7001EMSE#TRPBF require an external bootstrap diode?
No, the LTC7001EMSE#TRPBF does not require an external bootstrap diode because it contains an internal charge pump that actively regulates the BST–TS voltage to 12V. This enables true 100% duty cycle operation and eliminates diode-related leakage, reverse recovery, and layout complexity - unlike conventional bootstrap gate drivers.
How is the VCC undervoltage lockout threshold set on the LTC7001EMSE#TRPBF?
The VCC undervoltage lockout threshold on the LTC7001EMSE#TRPBF is set using a resistor from the VCCUV pin to GND. An internal 10µA current source generates a voltage across this resistor; the rising UVLO threshold equals 7× that voltage. With VCCUV open, the threshold defaults to 7.0V. Values between 3.5V and 10.5V are achievable using resistors from ~50kΩ to ~150kΩ.
Can the LTC7001EMSE#TRPBF drive a MOSFET with 10nF gate capacitance?
Yes, the LTC7001EMSE#TRPBF can drive a MOSFET with 10nF gate capacitance: its 1Ω pull-down and 2.2Ω pull-up drivers deliver fast transitions - e.g., 90ns fall time and 40ns rise time into 10nF (per datasheet). For optimal performance, ensure adequate BST capacitance (≥0.1µF) and minimize gate loop inductance in PCB layout.
Is the LTC7001EMSE#TRPBF pin-compatible with other members of the LTC700x family?
No, the LTC7001EMSE#TRPBF is not pin-compatible with LTC7000 or LTC7002. While all share the same 10-lead MSOP package and core functionality, pin assignments differ - notably, LTC7000 uses different pinouts for OVLO and VCCUV, and LTC7002 adds a separate EN pin. Always verify pin mapping against the specific device's datasheet before board reuse.
