Rated for operation from -40°C to 105°C, it fits industrial environments such as motor drives, outdoor telecom equipment, and factory automation panels where the rail must be asserted before the system starts. ## Open-drain output — wired-OR flexibility The open-drain output lets the BD48L42G-TL pull the reset line low without sourcing current, making it suitable for mixed-voltage systems where the reset signal needs to be shared across multiple supervisors or pulled up to a different supply rail. ## Package and footprint Supplied in a surface-mount SOT-23-3 package (also referred to as TO-236-3 or SC-59), with the supplier device package listed as 3-SSOP. The three-pin footprint — VDD, GND, and open-drain output — keeps the board layout simple; no external pull-up resistor is needed if the downstream logic already has a pull-up on the line.","metaTitle":"BD48L42G-TL Voltage Detector, 4.2V Threshold, Active Low","metaDescription":"BD48L42G-TL voltage detector from the BD48Lxx series. 4.2V threshold, active-low open-drain output.
