Overview
The NCP432BVSNT1G is a programmable precision shunt voltage reference from onsemi, housed in an SOT-23-3 surface-mount package. It features an adjustable output voltage capability with an initial accuracy of 0.5% and a temperature coefficient of 50 PPM/C. The device supports a maximum input voltage of 36 V and can handle a maximum shunt current of 100 mA. It operates within an extended temperature range from -40°C to +125°C. This component belongs to the NCP431 series and is classified under PMIC voltage references.
Feature Summary
- Provides adjustable precision voltage referencing via shunt regulation architecture
- Ensures stable performance across wide industrial temperature ranges
- Delivers high initial accuracy for precise circuit calibration needs
Applications
- Portable equipment power supply monitoring
- Battery-operated systems requiring accurate voltage tracking
- General-purpose voltage reference circuits in compact designs
Procurement Notes
Verify the specific suffix 'BV' against official datasheets to confirm the exact temperature grade and accuracy bin, as variations exist within the NCP432 family. Ensure the ordering quantity aligns with standard reel sizes if bulk procurement is intended. Cross-reference the manufacturer part number with distributor codes to avoid substitution errors during sourcing.
Selection Notes
Select this component when an adjustable shunt reference is required in a small SOT-23-3 footprint. It is suitable for applications demanding operation up to 36 V input and high thermal stability. Compare against fixed-voltage alternatives if the design does not require programmability. Consider the 0.5% initial accuracy tolerance for critical analog signal paths.
Part Context
This part is part of the NCP431 series, which includes various programmable shunt references. It shares architectural similarities with other members like the NCP431BVSNT1G but differs in specific electrical characteristics and temperature ratings. The series is designed for cost-sensitive, space-constrained power management applications requiring reliable voltage regulation.
Replacement Considerations
NCP432BCSNT1G offers similar specifications but with a limited commercial temperature range (0°C to +70°C). SC432BVSNT1G provides automotive-grade qualification with comparable electrical parameters. Verify temperature range requirements before substituting.
