Overview
The NLAS52231 is a dual SPDT analog switch featuring overshoot protection on signal lines. It operates within a VCC range of 1.65 V to 4.5 V and supports control input voltages as low as 1.3 V at VCC = 3.0 V. The device provides ultra-low on-resistance, with RON values of 0.4 Ω at VCC = 4.2 V and 0.38 Ω for the NO channel at VCC = 3.0 V. Overshoot tolerance allows VIS to safely rise up to 1.1 V above VCC. Turn-on time is typically 50 ns, while turn-off time is typically 30 ns. The maximum quiescent supply current is ±2.0 µA across the operating temperature range of -40°C to +85°C.
Feature Summary
- Overshoot protection enables safe signal handling above nominal VCC levels without distortion or leakage.
- Ultra-low on-resistance ensures maximum signal transfer efficiency in audio applications.
- Wide supply voltage range supports direct interfacing with various digital logic levels.
Applications
- Mobile phones
- Portable devices
Procurement Notes
Verify the ordering suffix 'MUR2G' corresponds to the UQFN10 package and tape & reel shipping configuration containing 3000 units per reel. Confirm the component is lead-free (Pb-Free) as indicated by the specific marking code. Ensure the datasheet revision matches the design requirements before finalizing procurement documentation.
Selection Notes
Select this component when designing circuits requiring dual SPDT switching with low insertion loss. The overshoot protection feature is critical for audio paths where signal spikes may exceed the supply rail. Verify that the required on-resistance flatness and off-channel isolation meet the system's signal integrity specifications under the intended operating voltage conditions.
Part Context
This part belongs to the NLAS5 series of ultra-low power analog switches from onsemi. It shares the same functional core as the NLAS5223 but adds specific overshoot protection capabilities. The device is housed in a compact 1.4 mm x 1.8 mm UQFN10 package, designed for space-constrained portable electronics.
Replacement Considerations
Public confirmed substitute: NLAS5223LMNR2G. Note that the NLAS5223 lacks the overshoot protection feature found in the NLAS52231. Verify if the absence of overshoot tolerance impacts the target application's signal integrity requirements before substitution.
