Acs758Lcb 050B Hall Effect Based Linear Current Sensor Ic

Rs. 425.00 Rs. 510.00

-ACS758LCB-050B Hall-Effect-Based Linear Current Sensor IC offers affordable and precise solutions for AC or DC contemporary sensing.
-Typical packages include motor manipulate, load detection and control, strength deliver and DC-to-DC converter control, inverter manage, and overcurrent fault detection.

Features:
Integrated protect greatly reduces capacitive coupling from the contemporary conductor to die due to excessive dV/dt indicators, and stops offset glide in excessive-side, excessive-voltage applications.
Total output mistakes development via gain and offset trim over temperature.
Small package deal length, with easy mounting functionality.
Monolithic Hall IC for high reliability.
Output voltage proportional to AC or DC currents.
Factory-trimmed for accuracy.
Extremely stable output offset voltage.
Nearly 0 magnetic hystereses.
SPECIFICATIONS:
Maximum Supply Voltage       5.5 V
Minimum Supply Voltage       3 V
Operating Current            10 mA
Operating Temperature Range  –40°C to 150°C

OVERVIEW:

-Integrated shield greatly reduces capacitive coupling from the current conductor to die due to high dV/dt signals, and prevents offset drift in high-side, high-voltage applications.

-Total output error improvement through gain and offset trim over temperature.

-Small package size, with easy mounting capability.

-Monolithic Hall IC for high reliability.

-Output voltage proportional to AC or DC currents.

-Factory-trimmed for accuracy.

-Extremely stable output offset voltage.

-Nearly zero magnetic hystereses.


PACKAGE INCLUDES:

1 PCS x Acs758Lcb 050B Hall Effect Based Linear Current Sensor Ic
