Compact, environment friendly, and automotive-grade, the gadget allows lighter wiring, decreased standby present, and extra dependable energy for ECUs, sensors, and safety-critical electronics in fashionable automobiles.
ABLIC Inc., has launched the S-19230/1 Sequence, a high-withstand voltage LDO linear regulator IC designed for the following wave of 48V automotive auxiliary batteries. The gadget achieves an industry-low 2.0µA working present, addressing rising calls for for energy-efficient automobile electronics.
With automobiles integrating extra ECUs, infotainment methods, and always-on sensors, auxiliary batteries are shifting from 12V to 48V methods. This larger voltage slashes present necessities to one-quarter, enabling lighter wire harnesses, decreased copper use, and improved gas and energy effectivity. Key Options embrace:
- Business-low 2.0µA working present; 0.1µA power-off present
- Large enter voltage: 6–66V (3V min. at ≤10mA), withstands surges as much as 80V
- Adjustable output voltage: 1.8–12V with ±1.8% accuracy
- Built-in open-loop, overcurrent, and thermal safety
- Automotive-grade design for ECUs, sensors, ABS, transmissions, EV/HEV/PHEV methods
The brand new regulator collection helps 80V enter tolerance, making it appropriate not just for 48V but in addition for 24V and 12V auxiliary batteries. Its extraordinarily low quiescent present helps curb standby energy drain, a vital issue for powering sensors, CAN/LIN transceivers, and safety-critical modules even when the ignition is off.
A key differentiator is the regulator’s built-in open-loop safety circuit. This security function prevents runaway voltages in case of wiring faults, eliminating the necessity for exterior overvoltage parts. The consequence: fewer components, decrease value, and extra compact designs with out compromising security.
The Sequence delivers as much as 100mA output present, whereas the opposite variant doubles that to 200mA. Each keep tight voltage accuracy throughout harsh automotive situations (–40°C to +125°C). The ICs can be found in TO-252-5S(A), HSOP-8A, and HTMSOP-8 packages, supporting versatile integration into fashionable ECUs. The corporate additionally ensures reliability with three-temperature testing and plans for AEC-Q100 qualification and PPAP compliance, aligning with stringent automotive {industry} necessities.
By merging ultra-low energy consumption with built-in safety and vast voltage help, the newest regulator positions itself as a vital enabler of the lighter, safer, and extra environment friendly automobiles shaping the way forward for mobility.
