ROHM Semiconductor Unveils Automotive Grade Load Switch IC
ROHM Introduces Advanced Single-Channel High-Side Load Switch for Automotive Applications: BV1HAC85EFJ-C
ROHM has recently launched the BV1HAC85EFJ-C, a state-of-the-art single-channel high-side load switch designed for robust power management in automotive systems. This N-channel MOSFET high-side load switch operates within an input voltage range of 8.0V to 28.0V, providing versatile power control for a variety of automotive applications.
The BV1HAC85EFJ-C integrates comprehensive protection features, including overcurrent protection, thermal shutdown protection, a soft-start function, and a low-power output OFF function. An error flag notification pin is also included to provide real-time status updates on thermal shutdown and overcurrent events, enabling efficient single-chip power management.
This advanced load switch is housed in a compact surface-mount HTSOP-J8 package, measuring 4.9mm x 6.0mm x 1.0mm, making it suitable for applications with space constraints. It is designed to handle resistive, inductive, and capacitive loads, ensuring compatibility with diverse automotive systems.
Key Features of the BV1HAC85EFJ-C:
- AEC-Q100 Qualified: Meets stringent automotive industry standards for reliability and durability.
- Functional Safety Supportive Automotive Products: Designed to enhance the safety of automotive electronic systems.
- Dual TSD (Thermal Shutdown): Enhanced thermal protection for reliable operation.
- Low On-Resistance Single Nch MOSFET Switch: Minimizes power loss and improves efficiency.
- Variable Output Soft-Start Time: Allows for controlled power delivery to prevent inrush current.
- Overcurrent Protection Function (Latch-Off): Protects the system from excessive current.
- Thermal Shutdown Protection Function (TSD): Prevents overheating and potential damage.
- Low Voltage Output OFF Function (UVLO): Ensures stable operation under low voltage conditions.
- Error Flag Notification Pin: Provides real-time feedback on fault conditions.
