Main Attributes and Operational Overview of the LTC7004MPMSE#PBF

The LTC7004MPMSE#PBF is characterized by its fast N-channel MOSFET gate driving capability, enabling efficient turn-on and turn-off with propagation delays as short as 35ns. Key features include:

Wide input (TS) operating range from 0V to 60V, supporting diverse power architectures.

Integrated charge pump supporting 100% duty cycle operation, ensuring continuous MOSFET gate enhancement even when the source potential moves up to the input supply.

Adjustable gate driver supply (VCC) voltage from 3.5V to 15V for optimal logic-level adaptation and driving larger gate capacitances efficiently.

Adjustable undervoltage and overvoltage lockout thresholds for both gate drive (VCCUV pin) and input supply (OVLO pin), facilitating custom protection schemes.

Strong 2.2Ω (pull-up) and 1Ω (pull-down) gate driver outputs suited for rapid switching of even large MOSFETs.

CMOS compatible logic input (INP), ensuring straightforward interface with standard control logic.

Internal protection mechanisms including thermal shutdown, supply undervoltage lockout, and bootstrap voltage monitoring to prevent out-of-range or fault conditions from propagating to the power stage.

The LTC7004MPMSE#PBF's strong driver architecture is particularly suited to applications needing low conduction losses, high switching speed, or static on-state control, such as load, supply, and electronic valve drivers.

Electrical and Heat Dissipation Specifications of the LTC7004MPMSE#PBF

The LTC7004MPMSE#PBF demonstrates impressive electrical robustness and efficiency:

Input supply (TS) spans 0V to 60V, suitable for high-voltage rail switching.

The device operates with a quiescent supply current as low as 225μA during regulation, dropping to 27–50μA in sleep mode for power-conscious designs.

The integrated charge pump maintains the high-side gate drive even at low VCC (down to 3.5V), supporting efficient gate turn-on without sacrificing speed.

Output rise and fall times are as fast as 13ns (with 1nF load), and the propagation delay between input command and output is typically 35ns, making it viable for high-frequency designs.

Absolute maximum junction temperature is 150°C (rated for operation down to –55°C), ensuring suitability for harsh automotive and industrial environments.

Thermal resistance is low (θJA = 45°C/W, θJC = 10°C/W with exposed pad soldered), supporting high power density integration and effective heat dissipation.

System designers have granular control over undervoltage and overvoltage lockout thresholds using external resistor dividers, improving flexibility and safety.

Assembly Details, Packaging, and Pin Layout of the LTC7004MPMSE#PBF

Housed in a compact 10-lead MSOP package with an exposed ground pad for enhanced heat dissipation, the LTC7004MPMSE#PBF is optimized for dense PCB layouts and low inductance connections—a key advantage for high dV/dt switching environments. The critical pins include:

VCC: Main gate driver supply (3.5V to 15V).

VCCUV: Programmable undervoltage lockout; external resistor programs gate-on threshold.

INP: CMOS-compatible control input.

TGUP/TGDN: High current outputs for MOSFET gate drive, directly driving the gate between BST and TS.

BST/TS: High-side bootstrap supply and source reference, facilitating high-voltage operation.

Exposed PAD: Must be soldered to PCB ground for thermal and electrical performance.

The recommended minimum bypass capacitance (e.g., 0.1μF on VCC and BST-TS) ensures reliable charge storage and transient response.

Possible Applications and Implementation Examples of the LTC7004MPMSE#PBF

The LTC7004MPMSE#PBF supports a wide range of high-voltage, high-speed, and static switch control applications, such as:

High-side or synchronous rectification in high-efficiency DC/DC converters for telecom and server infrastructure.

Supply and battery disconnect/selection stages where low gate driver quiescent current is crucial to extend operating life between cycles.

Use in environments requiring AEC-Q100 automotive qualificaton (available for certain variants), supporting extended temperature operations and system reliability requirements.

Engineers benefit from the ability to program undervoltage and overvoltage lockout points, optimizing system-level protection tailored to the specific application voltage ranges and operational priorities.

Alternative or Comparable Models to the LTC7004MPMSE#PBF

When selecting a high-side gate driver for NMOS static switch applications, alternative models may be considered based on availability or specific feature requirements. In Analog Devices’ portfolio, compatible models include:

LTC7004EMSE#PBF, LTC7004IMSE#PBF, LTC7004HMSE#PBF, which cover different guaranteed operating temperature ranges (from –40°C to 125°C, up to –40°C to 150°C).

Automotive-qualified variants, such as the LTC7004IMSE#WPBF and LTC7004JMSE#WPBF, support AEC-Q100 for vehicular use cases.

For applications requiring lower voltage or different packaging, engineers might also review other gate driver ICs within the Analog Devices “Power by Linear” series, matching supply, speed, and package constraints.
