Product details
Overview
LTC7004HMSE#TRPBF from Analog Devices is a fast 60V high-side N-channel MOSFET gate driver with internal charge pump, enabling 100% duty cycle operation. It features 1Ω pull-down and 2.2Ω pull-up drivers, 35ns propagation delay, and operates from 3.5V to 15V VCC supply. Designed for automotive-grade static switch and load switching applications up to 150°C junction temperature.
For engineers reviewing the LTC7004HMSE#TRPBF datasheet, LTC7004HMSE#TRPBF pinout, LTC7004HMSE#TRPBF application, or LTC7004HMSE#TRPBF equivalent, key selection criteria include TS voltage range (0–60V), adjustable VCC undervoltage lockout via VCCUV pin, OVLO threshold programmability, thermal rating (–40°C to 150°C), and MSOP-10 exposed-pad package compatibility with high-voltage PCB layout requirements.
Technical Context
The LTC7004HMSE#TRPBF integrates a self-regulating charge pump that maintains BST–TS at ~12V, enabling indefinite high-side NMOS conduction without external bootstrap diode dependency. Its level-shifted output stage delivers rail-to-rail gate drive with independently routed TGUP (pull-up to BST) and TGDN (pull-down to TS) terminals.
Protection logic includes three independent undervoltage monitors: VCCUV-configurable VCC lockout (3.5–10.5V rising threshold), OVLO-pin-based input overvoltage lockout (1.11–1.21V threshold), and BST–TS floating UVLO (3.1V typical). All trigger TGDN pull-down to TS to force external MOSFET off.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range (TS) | 0 V to 60 V - supports high-side switching in 24 V, 48 V, and 60 V industrial/automotive power rails. |
| VCC Supply Range | 3.5 V to 15 V - compatible with standard logic supplies and allows direct connection to 5 V or 12 V system rails. |
| TG Pull-Up / Pull-Down RDS(ON) | 2.2 Ω / 1 Ω - enables fast turn-on/off of large-gate-capacitance MOSFETs (e.g., QG > 50 nC) with minimal transition loss. |
| Propagation Delay | 35 ns (typ.) - ensures precise timing control in high-frequency switching or critical safety-cutoff applications. |
| Operating Junction Temp | –40°C to +150°C - qualified per AEC-Q100 Grade H, suitable for under-hood automotive and high-temp industrial environments. |
| Charge Pump Output | Regulates BST–TS to ~12 V - sustains full gate overdrive (VGS) across entire duty cycle, eliminating shoot-through risk in static switch mode. |
| Input Threshold (VIH/VIL) | 2.0 V / 1.6 V with 400 mV hysteresis - provides noise-immune CMOS-compatible control interface, independent of VCC variation. |
Pinout & Package
Package: 10-lead plastic MSOP with exposed thermal pad (Pin 11 = GND), rated for 45°C/W θJA. Exposed pad must be soldered to PCB ground plane for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Main logic supply input | Accepts 3.5–15 V; powers internal logic, charge pump, and level shifter; requires ≥0.1 µF bypass to GND. |
| VCCUV (Pin 2) | VCC undervoltage lockout reference | Resistor-to-GND sets rising VCC UVLO threshold between 3.5 V and 10.5 V; open = 7.0 V default. |
| GND (Pin 3 & Exposed Pad 11) | Ground reference and thermal path | Primary return for all internal circuits; exposed pad is mandatory GND connection for thermal derating and EMI control. |
| INP (Pin 4) | Digital enable input | CMOS-compatible control signal (VIH = 2.0 V); internal 1 MΩ pull-down holds TGDN low during startup. |
| OVLO (Pin 5) | Input overvoltage detection input | Resistive divider from VIN sets lockout threshold (1.11–1.21 V); >1.21 V forces TGDN to TS, disabling MOSFET. |
| TGDN (Pin 6) | High-current gate pull-down output | Directly connects to MOSFET gate for fastest turn-off; sinks current to TS (not GND) in high-side configuration. |
| TGUP (Pin 7) | High-current gate pull-up output | Drives gate toward BST voltage; used with series resistor for slew-rate control during turn-on. |
| TS (Pin 8) | Top-side source reference | Connects to MOSFET source terminal; serves as local ground reference for high-side driver stage; tolerates –6 V to +65 V. |
| BST (Pin 9) | Bootstrapped supply output | Charged by internal pump to ~12 V above TS; supplies gate drive voltage; requires ≥0.1 µF capacitor to TS. |
| NC (Pin 10) | No-connect | Must remain unconnected; no internal circuitry attached. |
Key Features
| Feature | Design Value |
|---|---|
| 100% duty cycle support | Internal charge pump maintains stable BST–TS voltage regardless of duty cycle-enables true static high-side switching without external diode or capacitor charging limitations. |
| Adjustable slew rate control | TGUP pin allows series resistor insertion to limit dV/dt during MOSFET turn-on-reduces EMI and inrush current in capacitive loads. |
| Triple-stage protection | Independent VCCUV, OVLO, and BST–TS UVLO monitors all force TGDN to TS-ensures fail-safe shutdown under supply fault, overvoltage, or charge pump failure. |
| AEC-Q100 Grade H qualification | Validated for –40°C to +150°C operation with extended reliability testing-meets automotive under-hood thermal and lifetime requirements. |
| High-voltage robustness | TS pin rated –6 V to +65 V; INP pin rated –6 V to +15 V-tolerates inductive kickback and PCB trace ringing in 60 V systems. |
Applications
| Automotive Load Switch | Industrial High-Voltage Power Sequencing |

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 12 V gate drive; no internal charge pump; requires external bootstrap diode; max TS = 100 V but no BST–TS UVLO. | Lacks 100% duty cycle support and integrated OVLO/VCCUV programming; suited for lower-cost, non-automotive applications with simpler protection needs. | Select when cost sensitivity outweighs need for integrated charge pump and programmable lockouts; verify external diode placement and thermal management. |
| MAX15066AATA+ | Integrated 12 V LDO for VCC; no adjustable VCCUV/OVLO; only 105°C max junction temp; no exposed thermal pad. | Not AEC-Q100 qualified; lacks high-temp rating and thermal performance for under-hood use; limited to commercial/industrial ambient conditions. | Choose only for space-constrained, non-automotive designs where 105°C operation suffices and external LDO simplifies supply design. |
Compared with LM5109BMM/NOPB and MAX15066AATA+, the LTC7004HMSE#TRPBF uniquely combines AEC-Q100 Grade H qualification, fully integrated charge pump with BST–TS UVLO, and dual-programmable lockout inputs-making it the only option supporting robust 150°C static switching with zero external protection components in automotive and harsh industrial settings.

FAQ
What is the maximum TS voltage rating for the LTC7004HMSE#TRPBF?
The LTC7004HMSE#TRPBF supports TS voltages from –6 V to +65 V, with normal operation specified from 0 V to +60 V. This rating enables safe use in 48 V automotive systems and industrial 60 V DC buses, including tolerance for inductive kickback transients below ground.
Does the LTC7004HMSE#TRPBF require an external bootstrap diode?
No, the LTC7004HMSE#TRPBF does not require an external bootstrap diode. Its integrated charge pump autonomously maintains BST–TS at ~12 V, enabling true 100% duty cycle operation without external diode dependency-unlike legacy high-side drivers such as the LM5109B.
How is the VCC undervoltage lockout threshold set on the LTC7004HMSE#TRPBF?
The VCC undervoltage lockout threshold on the LTC7004HMSE#TRPBF is set via a resistor from VCCUV (Pin 2) to GND. The internal 10 µA current source generates a voltage across this resistor, scaling the rising lockout threshold from 3.5 V to 10.5 V. An open VCCUV pin defaults to 7.0 V.
What is the purpose of the NC pin (Pin 10) on the LTC7004HMSE#TRPBF?
Pin 10 of the LTC7004HMSE#TRPBF is a no-connect (NC) terminal with no internal connection. It must remain unconnected and floating in all designs-soldering or routing to any net may cause unpredictable behavior or damage due to internal isolation constraints.
Can the LTC7004HMSE#TRPBF drive GaN FETs effectively?
Yes, the LTC7004HMSE#TRPBF can effectively drive enhancement-mode GaN FETs. Its 1Ω pull-down and 2.2Ω pull-up drivers deliver <13 ns rise/fall times into 1 nF loads, and its regulated 12 V BST–TS output ensures optimal VGS overdrive-critical for minimizing GaN switching losses at high frequencies.
