## **Product Datasheet** 

The LPSR Series current sensors are tailored for smallcurrent measurement with integrated protection functionality. Designed for DC, AC, and pulsed current sensing up to 50A, LPSR parts rely on closedloop Halleffect technology with an integrated primary conductor and reference voltage access. 

A key differentiator of the LPSR Series is its overcurrent detection output, allowing direct monitoring of abnormal current conditions  at  system  level.  The  4pin  primary  footprint  increases  creepage  and  clearance  distances  to  9.9  mm, supporting high insulation requirements. These features make the LPSR Series especially suitable for industrial power and control applications where both measurement and protection are critical. 

## **Main characteristics** 

- Closed loop multi-range current transducer 

- Voltage output 

- Unipolar supply voltage 

- Compact design for PCB mounting 

- Overcurrent detect at 4.1 × I P N. 

- Cost attractive 

- PCB mounting in various footprints (3 or 4 primary pins with various layouts) 

- With integrated primary conductors 

- Compact design 

- High overall accuracy at +105°C up to 2% 

## **Benefits** 

- Very low offset drift 

- Very good dv/dt immunity 

- Fast response time <0.4 µs 

- Reference pin with two modes: Ref IN and Ref OUT 

- Extended measuring range for unipolar measurement 

## **Typical applications** 

LPSR products are engineered for industrial use, fulfilling a range of functions across various applications: 

- AC variable speed and servo motor drives 

- Static converters for DC motor drives 

- Battery supplied applications 

- Uninterruptible Power Supplies (UPS) 

- Switched Mode Power Supplies (SMPS) 

- Power supplies for welding applications 

- Solar inverters
