Product details
Overview
LTC7001IMSE#TRPBF from Analog Devices is a fast high-side N-channel MOSFET gate driver IC designed for static and high-frequency switching in 135V input systems. It features an internal charge pump enabling 100% duty cycle operation, 1Ω pull-down / 2.2Ω pull-up drive strength, 35ns propagation delay, and operates with VTS up to 135V (150V abs max). It is used in automotive-grade high-voltage load switching applications requiring robust overvoltage and undervoltage protection.
For engineers reviewing the LTC7001IMSE#TRPBF datasheet, LTC7001IMSE#TRPBF pinout, LTC7001IMSE#TRPBF application, or LTC7001IMSE#TRPBF equivalent, key selection criteria include its 150V absolute maximum TS rating, adjustable OVLO/VCCUV thresholds, thermally enhanced MSOP-10 package with exposed GND pad, and AEC-Q100 qualification for automotive use.
Technical Context
The LTC7001IMSE#TRPBF integrates a high-voltage level shifter and charge pump to drive external N-MOSFETs with gate voltages referenced to a floating TS node up to 135V. Its dual-output architecture separates TGUP (pull-up to BST) and TGDN (pull-down to TS), enabling independent slew rate control during turn-on and guaranteed fast turn-off.
Protection logic includes three independent undervoltage lockouts: VCCUV-configurable VCC UVLO (3.5–10.5V), OVLO-pin-based input overvoltage detection (1.11–1.21V threshold), and BST-TS floating UVLO (3.1V typical). All lockouts force TGDN to TS, ensuring fail-safe shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VTS Range | 0V to 135V continuous; enables direct connection to high-side source of 135V bus without level-shifting circuitry. |
| Driver RON | Pull-up: 2.2Ω typ; Pull-down: 1Ω typ - delivers >1A peak current into 1nF load for sub-50ns transitions. |
| Propagation Delay | 35ns typ (INP to TG output) - supports high-frequency PWM control and fast fault response. |
| Charge Pump Output | Regulates BST–TS to 12V - sustains 100% duty cycle gate drive without external bootstrap diode. |
| UVLO Thresholds | VCCUV-adjustable (3.5–10.5V rising); OVLO threshold 1.21V rising - allows precise system-level supply monitoring. |
| Operating Temp | –40°C to +125°C junction - qualified per AEC-Q100 Grade I for under-hood automotive power distribution. |
| Package | 10-lead MSOP with exposed thermal pad - θJA = 45°C/W; requires soldered GND pad for rated thermal performance. |
Pinout & Package
Package: 10-lead plastic MSOP (MSE), thermally enhanced, with exposed GND pad (Pin 11) that must be soldered to PCB for electrical integrity and thermal dissipation (θJA = 45°C/W, θJC = 10°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (1) | Main logic supply input | Accepts 3.5V–15V; powers internal logic and charge pump; bypass with ≥0.1µF to GND. |
| VCCUV (2) | VCC undervoltage reference | Resistor-to-GND sets rising VCC UVLO threshold between 3.5V–10.5V; open = 7.0V. |
| GND (3) | Logic ground reference | Reference for INP, OVLO, VCCUV; connects to exposed pad (Pin 11) - must be soldered. |
| INP (4) | CMOS-compatible enable input | Active-high digital signal (VIH = 2.0V typ); internal 1MΩ pull-down holds TGDN low at startup. |
| OVLO (5) | Input overvoltage sense | Resistive divider from VIN sets lockout at 1.21V rising; pulls TGDN to TS when exceeded. |
| TGDN (6) | High-current pull-down output | Drives external MOSFET gate to TS; 1Ω RDS(ON) ensures fast, robust turn-off. |
| TGUP (7) | High-current pull-up output | Drives gate to BST; 2.2Ω RDS(ON); series resistor enables adjustable turn-on slew rate. |
| TS (8) | High-side source terminal | Connects to MOSFET source; supports –6V to +150V range; handles inductive kickback. |
| BST (9) | Bootstrapped supply rail | Charged by internal pump to VTS + 12V; requires ≥0.1µF capacitor to TS. |
| NC (10) | No-connect | Must be left floating; no internal connection. |
Key Features
| Feature | Design Value |
|---|---|
| 100% duty cycle capability | Internal charge pump maintains BST–TS at 12V regardless of TS voltage - eliminates need for external bootstrap diode. |
| Adjustable turn-on slew rate | Series resistor on TGUP enables controlled dV/dt at MOSFET gate - reduces EMI and inrush in capacitive loads. |
| AEC-Q100 Grade I qualification | Validated for automotive applications across –40°C to +125°C junction temperature - supports ISO/TS 16949 production. |
| Triple independent UV/OV protection | VCCUV, OVLO, and BST-TS UVLO circuits independently monitor supply health - all force TGDN to TS for fail-safe shutdown. |
| High-voltage TS tolerance | TS pin rated –6V to +150V - withstands inductive flyback and transient ringing in 135V systems without clamping diodes. |

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 VHS (60V), no integrated charge pump, requires external bootstrap diode; 50ns propagation delay. | Suitable only for ≤60V systems; lacks AEC-Q100 qualification and adjustable OVLO/VCCUV. | Select only for cost-sensitive non-automotive designs where 135V operation and 100% duty cycle are not required. |
| MAX25602AUB+ | Higher integration (integrated MOSFET), 100V max VIN, fixed 5V gate drive; no separate TGUP/TGDN pins. | Targeted at compact DC-DC controllers; not a standalone gate driver - cannot replace LTC7001IMSE#TRPBF in discrete MOSFET configurations. | Use only when board space is constrained and integrated solution suffices; not a functional substitute for discrete high-side driving. |
Compared with LM5109BMM/NOPB and MAX25602AUB+, the LTC7001IMSE#TRPBF uniquely combines 135V TS rating, internal charge pump for 100% duty cycle, AEC-Q100 qualification, and fully configurable protection thresholds - making it the only option for automotive and industrial 100–135V static switching with fail-safe monitoring.

FAQ
What is the absolute maximum voltage rating for the TS pin on the LTC7001IMSE#TRPBF?
The TS pin of the LTC7001IMSE#TRPBF has an absolute maximum rating of –6V to +150V. This allows direct connection to high-side sources in 135V systems while tolerating inductive flyback transients down to –6V. Operation beyond these limits risks permanent damage, and the device's internal protection does not extend to overvoltage conditions exceeding ±150V/–6V on TS.
Does the LTC7001IMSE#TRPBF require an external bootstrap diode?
No, the LTC7001IMSE#TRPBF does not require an external bootstrap diode because it contains an internal charge pump that regulates BST–TS to 12V, enabling true 100% duty cycle operation. An external silicon diode (e.g., MMBD1501A) is optional only if fast power-up or high-frequency (>500Hz) switching causes BST-TS collapse - Schottky diodes are prohibited due to excessive reverse leakage.
How is the VCC undervoltage lockout threshold set on the LTC7001IMSE#TRPBF?
The VCC undervoltage lockout threshold on the LTC7001IMSE#TRPBF is set via the VCCUV pin: connecting a resistor from VCCUV to GND programs the rising threshold between 3.5V and 10.5V using RVCCUV = (rising VCC UVLO)/70µA; leaving VCCUV open defaults to 7.0V. The falling threshold has ~600mV hysteresis, and both thresholds are temperature-stable across –40°C to +125°C.
Can the LTC7001IMSE#TRPBF drive a MOSFET gate directly without external components?
Yes, the LTC7001IMSE#TRPBF can drive a MOSFET gate directly: connect TGUP and TGDN to the gate, TS to the MOSFET source, and BST to TS via ≥0.1µF capacitor. However, for inrush control or oscillation damping, a series resistor on TGUP (and optionally a small RC network) is recommended - the IC's separated outputs allow this flexibility without compromising turn-off speed.
Is the LTC7001IMSE#TRPBF qualified for automotive applications?
Yes, the LTC7001IMSE#TRPBF is AEC-Q100 qualified for automotive applications (Grade I, –40°C to +125°C junction temperature) and manufactured under automotive quality systems. It includes built-in protection features - OVLO, VCCUV, BST-TS UVLO, and thermal shutdown - specifically validated for automotive load-dump, cold-crank, and transient immunity requirements.
