Product details
Overview
LTC7004IMSE#PBF from Analog Devices is a fast 60V high-side N-channel MOSFET gate driver IC with internal charge pump, enabling 100% duty cycle operation. It delivers 1Ω pull-down and 2.2Ω pull-up drive strength, 35ns propagation delay, and operates from 3.5V to 15V VCC supply - ideal for automotive load switch, electronic valve control, and high-frequency high-side switching in industrial power systems.
For engineers reviewing the LTC7004IMSE#PBF datasheet, LTC7004IMSE#PBF pinout, LTC7004IMSE#PBF application, or LTC7004IMSE#PBF equivalent, this page provides verified technical context, validated pin functions, confirmed thermal and electrical specifications, and real-world application constraints - all derived from Analog Devices' official Rev. C datasheet and package documentation.
Technical Context
The LTC7004IMSE#PBF integrates a self-regulating charge pump that maintains BST–TS at ~12V across TS voltages up to 60V, enabling indefinite high-side NMOS conduction without external bootstrap diodes. Its level-shifted output stage separates TGUP (pull-up to BST) and TGDN (pull-down to TS) for independent slew-rate control.
Protection logic includes adjustable VIN overvoltage lockout (via OVLO pin, 1.16V–1.26V threshold), programmable VCC undervoltage lockout (via VCCUV pin, 3.5V–10.5V range), and BST–TS floating UVLO (3.1V). The device features CMOS-compatible input with 400mV hysteresis and internal 1MΩ pull-down on INP.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 0V to 60V - supports direct connection to high-voltage DC bus without external level-shifting. |
| Gate Drive Output Resistance | TGUP: 2.2Ω typ, TGDN: 1Ω typ - enables <13ns rise/fall times into 1nF load, minimizing switching losses. |
| Propagation Delay | 35ns typ (INP to TG) - ensures precise timing control in fast-switching or safety-critical turn-on/turn-off sequences. |
| Charge Pump Output | Regulates BST–TS to 12V - sustains full gate enhancement of external NMOS even at 100% duty cycle. |
| VCC Supply Range | 3.5V to 15V - compatible with standard industrial and automotive supply rails; UVLO programmable via VCCUV pin. |
| Operating Temperature | –40°C to +125°C junction - qualified per AEC-Q100 Grade I, suitable for under-hood automotive and industrial environments. |
| 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) with exposed GND pad (Pin 11), thermally enhanced for high-power gate driving. Exposed pad must be soldered to PCB ground plane per Analog Devices layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Main 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 VCC UVLO threshold from 3.5V to 10.5V; open = 7.0V default. |
| GND (Pin 3 & Exposed Pad Pin 11) | Ground reference and thermal path | Primary signal and thermal return; exposed pad must be soldered for θJC = 10°C/W performance. |
| INP (Pin 4) | Digital input control | CMOS-compatible (VIH = 2.0V, VIL = 1.6V); internal 1MΩ pull-down holds TGDN low during startup. |
| OVLO (Pin 5) | Input overvoltage detection input | Resistive divider from VIN sets lockout at 1.16V–1.26V; 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 gate to BST (bootstrapped supply); 2.2Ω RDS(ON); series resistor enables adjustable turn-on slew rate. |
| TS (Pin 8) | High-side source reference | Connects to external MOSFET source; tolerates –6V to +65V; serves as local ground for high-side circuitry. |
| 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 be left floating; no internal connection or function. |
Key Features
| Feature | Design Value |
|---|---|
| 100% duty cycle capability | Internal charge pump maintains BST–TS at 12V regardless of TS voltage (0–60V), eliminating need for external bootstrap diode. |
| Adjustable turn-on slew rate | Series resistor between TGUP and MOSFET gate controls dV/dt, reducing EMI and inrush current in capacitive loads. |
| Programmable protection thresholds | Separate resistor networks on OVLO and VCCUV pins allow independent tuning of input overvoltage and VCC undervoltage lockouts. |
| Robust high-side operation | TGDN and TGUP outputs rated for ±65V transient tolerance on TS; withstands –6V undershoot during inductive turn-off. |
| AEC-Q100 qualification | Grade I (–40°C to +125°C) qualification confirms reliability for automotive load switching, battery disconnect, and e-valve control. |
Applications
| Automotive Load Switch | Industrial High-Side Power Control |

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; 50ns propagation delay; no OVLO/VCCUV adjustment. | Lacks programmable protection; unsuitable for true 100% duty cycle or automotive-grade thermal operation. | Select only if cost-sensitive and duty cycle <99%; verify external diode and capacitor sizing for required hold time. |
| MAX15012ATA+T | Integrated high-side driver with 100% duty cycle, but max VIN = 40V; 55ns propagation; no adjustable slew rate; no AEC-Q100 rating. | Lower voltage rating limits use in 48V+ automotive or industrial buses; lacks thermal grade for under-hood deployment. | Consider for 24V/36V systems where AEC-Q100 is not mandated; confirm BST regulation stability at 40V TS. |
Compared with LM5109BMM/NOPB and MAX15012ATA+T, the LTC7004IMSE#PBF uniquely combines 60V VIN tolerance, fully integrated charge pump, AEC-Q100 Grade I qualification, and independently adjustable OVLO/VCCUV - making it the only option for robust, programmable, 100%-duty-cycle high-side switching in demanding automotive and industrial environments.

FAQ
What is the maximum input voltage the LTC7004IMSE#PBF can handle on its TS pin?
The LTC7004IMSE#PBF supports TS pin voltages from –6V to +65V, enabling direct connection to 60V DC bus rails. This rating accommodates both normal operation (0–60V) and transient undershoot (down to –6V) during inductive turn-off - a key requirement for automotive and industrial high-side switching applications where load inductance causes negative flyback.
Does the LTC7004IMSE#PBF require an external bootstrap diode?
No, the LTC7004IMSE#PBF does not require an external bootstrap diode. Its integrated charge pump autonomously regulates BST–TS to ~12V across the full 0–60V TS range, enabling true 100% duty cycle operation. An external diode is only recommended if power-up time or high-frequency switching (>500Hz) risks BST–TS collapse - per Analog Devices' Application Note.
How is the VCC undervoltage lockout threshold set on the LTC7004IMSE#PBF?
The VCC undervoltage lockout threshold on the LTC7004IMSE#PBF is set via a resistor (RVCCUV) from Pin 2 (VCCUV) to GND. An internal 10µA current source generates a voltage on VCCUV; the rising UVLO equals 7× that voltage. With VCCUV open, the threshold defaults to 7.0V. Using RVCCUV = 50kΩ yields ~3.5V rising UVLO, while 100kΩ gives ~7.0V - matching the datasheet's 70µA scaling factor.
Can the LTC7004IMSE#PBF drive large gate capacitances effectively?
Yes, the LTC7004IMSE#PBF is explicitly characterized to drive 1nF loads with 13ns rise/fall times and 35ns propagation delay using a 12V BST–TS supply. Its 1Ω pull-down and 2.2Ω pull-up output stages deliver high peak current, minimizing transition losses. For >10nF loads, rise/fall times increase to 90ns/40ns - still suitable for most static and medium-frequency switching applications.
Is the LTC7004IMSE#PBF pin-compatible with other members of the LTC700x family?
No, the LTC7004IMSE#PBF is not pin-compatible with LTC7000, LTC7001, or LTC7003. While sharing the same 10-lead MSOP package, pin functions differ significantly - for example, LTC7000 uses a single TG output, whereas LTC7004 separates TGUP and TGDN for slew control. Substitution requires full schematic and layout review per Analog Devices' family-specific datasheets.
