Its reduced on-state resistance (Rds(on) as low as 6.8mΩ typ.) and compliance with automotive standards (AEC Qualified, RoHS compliant) establish this device as a dependable choice for engineers seeking to replace traditional relays, fuses, or discrete switch circuits.

BTS50060-1TEA Pin Layout and Functions

The BTS50060-1TEA features a pragmatic five-pin configuration optimized for integration and ease of use in control circuitry. Pin assignments are as follows:

Pin 1 (GND): The ground reference for the control chip, ensuring operational stability.

Pin 2 (IN): Accepts digital logic control (compatible with both 3.3V and 5V logic levels); setting this pin high activates the output power switch, supported by an internal pull-down resistor for input integrity.

Tab/Pin 3 (OUT): The protected high-side power output; designed to handle the full load current with robust protection.

Pin 4 (IS): This pin provides an analog sense current output as well as defined fault signals, enabling load current sensing and facilitating advanced diagnostics.

Pin 5 (Vs): The positive supply voltage input supplying the logical and power stages of the switch.

The layout and internal connections are tailored for surface-mount installation, emphasizing minimized path resistance and optimized thermal dissipation.

Key Product Specifications of BTS50060-1TEA

At its core, the BTS50060-1TEA delivers high power handling and resilience across challenging environments. The device supports a wide junction temperature range from -40°C to 150°C, with storage ratings extending down to -55°C. Absolute maximum ratings include a supply voltage tolerance from -0.3V to 28V, reverse polarity tolerance up to 16V, and energy dissipation capabilities designed for both single-pulse and repetitive inductive load switching. ESD robustness spans 2kV to 4kV (HBM) depending on pin configuration, and CDM resistance up to ±750V, making it highly suitable for environments prone to voltage transients.

Engineers must pay attention to PCB trace design to fully leverage the current-handling capabilities of the OUT pin, especially when dealing with high inrush load events. The BTS50060-1TEA integrates all necessary features to facilitate long product life, robust operation, and compliance with stringent reliability standards.

Over temperature shutdown: Prevents thermal runaway by disabling output under excessive junction temperatures.

Intelligent latch: An embedded logic ensuring fault conditions do not propagate unwanted switching cycles.

Reverse polarity, ground loss, and load loss protection: Hardware safeguards against common wiring errors and system faults.

ESD and over-voltage shielding: Ensures robustness against typical environmental transients.

Load diagnosis: Includes analog load current sense, open load detection at both ON and OFF states, short-to-battery detection, and accuracy enhancement by end-of-line calibration.

These features collectively contribute to simplified fault localization and faster maintenance cycles, streamlining commissioning and troubleshooting workflows in real-world installations.

BTS50060-1TEA Electrical Properties and Associated Relationships

The electrical performance profile of the BTS50060-1TEA supports precise system design. With a nominal supply voltage window between 6V and 19V, and typical stand-by current of just 5μA at room temperature, power efficiency is optimal for battery-driven and always-on circuits. Rds(on) sits at 6.8mΩ typical at standard conditions, rising to 12mΩ at maximum rated temperature. Load current at 100Hz PWM operation is specified at 13.5A, with short-circuit shutdown threshold at 60A.

Engineers must consider dependencies such as temperature drift, supply voltage boundaries, and switching frequency regimes to ensure long-term performance stability. Additionally, calibration of sense output and monitoring system responses to diagnostically driven events can enhance load control precision in application environments.

BTS50060-1TEA Package Information and Installation Guidance

Delivered in a PG-TO252-5-11 (DPAK with 4 leads + Tab) package, the BTS50060-1TEA is designed for automated surface-mount assembly. Its low profile and robust tab facilitate high-current PCB connections and efficient heat dissipation, crucial during sustained or pulsed high-load operation.

Engineers should assess thermal management strategies and ensure that board trace widths meet current requirements to avoid excessive heating and performance degradation over time. Pin assignment, pad design, and placement within the system must adhere to datasheet recommendations to fully exploit the device's protection features.

Alternative or Replacement Options for BTS50060-1TEA
