Automotive dual LDO/switch for remote power
The Maxim Integrated MAX16948AGTE/V+T is an adjustable dual LDO/switch IC designed for automotive systems and remote power applications. It is qualified to AEC-Q100, the automotive reliability standard, and operates over a -40°C to 105°C temperature range, making it suitable for under-hood and engine-bay environments where temperature extremes are routine. The device accepts a wide 4.5V to 28V supply rail, covering nominal 12V and 24V automotive buses with headroom for load-dump transients.
Supply current and package
Quiescent supply current is 2.1mA, a figure that matters for always-on modules in the vehicle where every milliamp counts against the battery-offload budget. The part comes in a 16-WQFN Exposed Pad package (16-TQFN 4x4 mm footprint) with surface-mount mounting. The exposed pad must be soldered to a thermal land on the PCB to dissipate heat from the dual regulator pass elements; a via array under the pad is standard practice for keeping junction temperature within limits at full load.
Lifecycle and sourcing reality
The MAX16948AGTE/V+T carries an Active product status with ROHS3 compliance. For BOM planning, the active status means standard lead times through distribution apply, and no special LTB inventory management is needed.
