Infineon BTS72004EPAXUMA1 High-Side Switch: Datasheet, Features, and Application Overview
The Infineon BTS72004EPAXUMA1 is a high-side power switch from Infineon’s extensive portfolio of intelligent switching solutions. Designed for robust performance in automotive and industrial applications, this device integrates two independent 40V, 4A channels with advanced protective functions and diagnostic capabilities. It is housed in a compact PG-TSDSO-14-37 package, making it suitable for space-constrained designs requiring reliable load management.
Key Features and Benefits
A standout feature of the BTS72004EPAXUMA1 is its dual-channel design, allowing independent control of two loads with minimal external components. Each channel supports a maximum continuous current of 4A and features a very low typical on-state resistance (RDS(on)) of 17 mΩ per channel, which significantly reduces power dissipation and improves system efficiency.
The device includes comprehensive diagnostic and protection functions such as over-current protection (OCP), over-temperature protection (OTP), and over-voltage protection (OVP), enhancing system reliability. It also offers current sense feedback for each channel with a programmable sense ratio, enabling precise load current monitoring without additional external sensing components.
Furthermore, the switch supports reverse battery protection (up to -40V) and features a load current feedback pin, making it well-suited for 12V and 24V automotive systems where electrical conditions can be harsh and variable.
Datasheet Overview
The datasheet for the BTS72004EPAXUMA1 provides detailed information on electrical characteristics, timing diagrams, application examples, and thermal performance. Key specifications include an operating voltage range from 5.5V to 40V, ESD protection compliant with automotive standards, and short-circuit protection with automatic restart. The device is AEC-Q100 qualified, ensuring it meets the stringent requirements for automotive electronics.
Application Overview
This high-side switch is ideal for a wide range of applications, including:
- Automotive systems: driving resistive, inductive, or capacitive loads such as lamps, motors, and heaters.
- Industrial automation: controlling solenoids, valves, and small DC motors.
- Power distribution units: managing multiple power outputs with diagnostic feedback.
Its ability to handle inrush currents and provide diagnostic information makes it particularly valuable in applications where predictive maintenance and system safety are critical.
The Infineon BTS72004EPAXUMA1 is a highly integrated, robust dual-channel high-side switch offering excellent efficiency, comprehensive protection, and diagnostic features, making it a top choice for automotive and industrial power management.
