Features

? High accurate, scalable, DC & AC current sensing

? Full scale up to ±34 mT for current measurements above 1000 A

? 5 V supply voltage

? Configurable differential analog output (including ratiometricity option)

? ISO 26262 Safety Element out of Context for safety requirements up to ASIL B

? Small form factor enables high power density

? Very low sensitivity error over temperature and lifetime

? Excellent stability of offset over temperature and lifetime

? Differential sensor principle ensures superior magnetic stray field suppression

? High bandwidth provides fast response time and low phase delay

? Over-Current Detection with configurable threshold (max detection time < 1.0 μs)

? EEPROM with integrated charge-pump for in-system programming and end-of-line calibration

without additional circuitry

read/write programming access to internal EEPROM, control of diagnosis mode

? Pre-calibrated over temperature with possibility of in-system end-of-line calibration to

compensate system-level errors

Potential applications

? Main and auxiliary electrical drives

? Over-load and over-current detection

? Battery main switch

? Smart circuit breakers

? PV inverters

? Current monitoring and power supplies

Description

TLE4973 is a high precision miniature coreless magnetic current sensor for AC and DC measurements with analog interface

and fast over-current detection output. Negative effects (saturation, hysteresis) known from open loop sensors using flux

concentration techniques are avoided. The differential measurement principle allows great stray field suppression for operation

in harsh environments. The high configurability enables customization for a variety of applications. User-programmable

parameters such as OCD thresholds and sensitivity settings are stored in an embedded EEPROM. Device configuration can

be performend in-situ through a one-wire UART based interface called Digital Control Diagnostic Interface (DCDI). The DCDI

interface provides read/write access to internal registers of the device and allows to trigger the diagnostic mode and to read

temperature, OCD and safety status. It has an auto-addressing functionality and can handle up to 8 slaves on one bus.
