Product details
Overview
LTC7004HMSE#PBF from Analog Devices is a high-voltage, high-side N-channel MOSFET gate driver IC designed for static and switching applications up to 60V input voltage. It integrates an internal charge pump enabling 100% duty cycle operation, features 1Ω pull-down and 2.2Ω pull-up drivers with 35ns propagation delay, and operates across –40°C to 150°C junction temperature - ideal for automotive load switch and electronic valve control.
For engineers reviewing the LTC7004HMSE#PBF datasheet, LTC7004HMSE#PBF pinout, LTC7004HMSE#PBF application, or LTC7004HMSE#PBF equivalent, key selection criteria include its 60V TS voltage rating, adjustable VCC undervoltage lockout via VCCUV pin, programmable OVLO threshold, gate drive slew rate control, and thermally enhanced MSOP package with exposed GND pad.
Technical Context
The LTC7004HMSE#PBF employs a high-speed level-shifting architecture with integrated charge pump to sustain BST–TS at 12V for indefinite high-side NMOS conduction. Its dual-output stage separates TGUP (P-ch pull-up to BST) and TGDN (N-ch pull-down to TS), enabling independent turn-on slew control and fast, robust turn-off under high dv/dt conditions.
Protection logic includes three independent UVLO monitors: VCCUV-configurable gate supply lockout (3.5V–10.5V rising), BST–TS floating UVLO (3.1V), and OVLO pin-triggered shutdown (1.21V rising threshold). All functions are validated across –40°C to 150°C for AEC-Q100-compliant automotive use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max TS Voltage | 60V - supports high-side switching in 48V automotive and industrial bus systems without external level-shifters. |
| TG Pull-Down RDS(ON) | 1Ω typical - ensures rapid MOSFET turn-off even with large gate capacitance (>1nF) and minimizes shoot-through risk. |
| TG Pull-Up RDS(ON) | 2.2Ω typical - enables controlled gate charging; combined with external series resistor allows precise inrush current limiting. |
| Propagation Delay | 35ns max - guarantees tight timing alignment between INP command and gate voltage transition in high-frequency PWM systems. |
| Charge Pump Output | Regulates BST–TS to 12V - sustains full gate overdrive for low-RDS(ON) enhancement of high-voltage NMOS FETs at 100% duty cycle. |
| Operating Junction Temp | –40°C to +150°C - qualified per AEC-Q100 Grade H, suitable for under-hood automotive and high-temp industrial environments. |
| VCC Supply Range | 3.5V to 15V - compatible with standard 5V/12V rails and supports wide-input auxiliary supplies. |
Pinout & Package
Package: 10-lead plastic MSOP with exposed thermal pad (Pin 11 = GND), θJA = 45°C/W, rated for 150°C max junction temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Main gate driver 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 UVLO threshold from 3.5V to 10.5V; open = 7.0V default. |
| GND (Pin 3 & Exposed Pad Pin 11) | Signal and thermal ground reference | Exposed pad must be soldered to PCB ground plane for thermal performance and electrical stability. |
| INP (Pin 4) | CMOS-compatible digital input | Active-high control signal (VIH = 2.0V typ); internal 1MΩ pull-down holds TGDN low during startup. |
| OVLO (Pin 5) | Input overvoltage lockout sense | Resistive divider from VIN sets shutdown threshold (1.21V rising); tie to GND if unused. |
| TGDN (Pin 6) | High-current gate pull-down output | Drives MOSFET gate directly to TS; 1Ω RDS(ON) ensures fast, low-loss turn-off. |
| TGUP (Pin 7) | High-current gate pull-up output | Drives gate toward BST; 2.2Ω RDS(ON); series resistor enables adjustable turn-on slew rate. |
| TS (Pin 8) | High-side source reference node | Connects to MOSFET source; tolerates –6V to +65V; serves as return for TGDN/TGUP outputs. |
| BST (Pin 9) | Bootstrapped supply output | Charged by internal pump to VTS + 12V; requires ≥0.1µF capacitor to TS for stable gate drive. |
| NC (Pin 10) | No-connect terminal | Must remain unconnected; no internal circuitry attached. |
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/capacitor refresh circuits. |
| Adjustable turn-on slew rate | Series resistor on TGUP enables controlled dV/dt at MOSFET gate - reduces EMI and inrush current in capacitive loads. |
| Triple-stage protection monitoring | Independent UVLO on VCC, BST–TS, and OVLO pins - prevents unsafe gate drive under fault conditions without external supervision. |
| Thermally enhanced MSOP package | Exposed GND pad lowers θJC to 10°C/W - enables >1W dissipation at 150°C junction temp with proper PCB copper area. |
| AEC-Q100 Grade H qualification | Validated for automotive under-hood operation (–40°C to +150°C) - meets stress test requirements for HTOL, TC, and ESD. |
Applications
| Automotive Load Switch | Industrial High-Side Power Valve |

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 TS = 65V; no OVLO/VCCUV adjustment. | Lacks programmable protection thresholds and 100% duty cycle support - suitable only for fixed-rail, non-automotive designs. | Select when cost sensitivity outweighs programmability needs and duty cycle <100%. |
| MAX15066AATA+ | Integrated 5V LDO; lower drive strength (4Ω pull-up/2Ω pull-down); max TS = 60V; no BST pin - uses internal charge pump only. | Designed for low-power microcontroller I/O interfacing; lacks high-current TGUP/TGDN separation for slew control. | Prefer for space-constrained, low-power systems where gate charge <5nC and slew control unnecessary. |
Compared with LM5109BMM/NOPB and MAX15066AATA+, the LTC7004HMSE#PBF uniquely combines adjustable OVLO/VCCUV, separated high-current outputs for slew tuning, and true 100% duty cycle via self-sustaining charge pump - making it the only choice for robust, programmable high-side switching in automotive and industrial 48V+ systems.

FAQ
What is the maximum TS voltage rating for the LTC7004HMSE#PBF?
The LTC7004HMSE#PBF supports a maximum TS voltage of 60V, verified across its full operating temperature range (–40°C to +150°C). This rating allows direct integration into 48V automotive and industrial bus systems without external voltage clamping or level-shifting circuitry. Absolute maximum TS voltage is 65V, but sustained operation above 60V violates the guaranteed specification.
How does the LTC7004HMSE#PBF achieve 100% duty cycle operation?
The LTC7004HMSE#PBF achieves 100% duty cycle using an internal charge pump that continuously regulates the BST–TS voltage to 12V, independent of TS potential. Unlike bootstrap-based drivers requiring periodic low-side conduction to refresh the capacitor, this architecture sustains gate overdrive indefinitely - enabling continuous conduction in static switch applications without layout constraints.
Can the LTC7004HMSE#PBF drive SiC or GaN MOSFETs?
Yes, the LTC7004HMSE#PBF can drive SiC and GaN MOSFETs, provided gate voltage requirements fall within its 12V BST–TS output and gate charge demand remains within the driver's current capability. Its 1Ω pull-down and 2.2Ω pull-up deliver fast transitions into typical SiC/GaN gate capacitances (<5nF), and the 35ns propagation delay supports high-frequency switching up to 1MHz.
What is the purpose of the NC pin (Pin 10) on the LTC7004HMSE#PBF?
Pin 10 of the LTC7004HMSE#PBF is designated NC (No Connect) and contains no internal circuitry. It must remain unconnected and electrically floating in all designs. Soldering or routing to this pin may cause unpredictable behavior or damage due to internal isolation boundaries - the exposed pad (Pin 11) and Pin 3 serve as the sole GND connections.
Is the LTC7004HMSE#PBF pin-compatible with other variants in the LTC7004 family?
Yes, the LTC7004HMSE#PBF shares identical pinout, footprint, and electrical interface with all LTC7004 variants (E, I, MP grades) in the 10-lead MSOP package. Differences are limited to temperature grade, screening, and reliability testing - allowing drop-in replacement across grades without PCB redesign or layout changes.
