概要

Description

ACS780KLRTR-150B-T is a high-current Hall-effect, galvanically isolated current sensor from Allegro Microsystems. In a KLR package (Tape & Reel), it carries up to 150 A through an internal conductor and provides isolation between the primary current path and the signal output. It outputs a ratiometric analog voltage proportional to the sensed current, typically centered at Vcc/2 for zero current, enabling bidirectional measurement on a single-supply system. Suitable for DC and low-frequency AC currents, it offers good temperature stability and common protection features. Common applications include motor drives, power supplies, battery management, DC-DC converters, and automotive power electronics. Packaging is RoHS-compliant. For exact electricals (supply range, sensitivity, isolation rating, and pinout), consult the ACS780KLRTR-150B-T datasheet.

Features

Here are the main features of the ACS780KLRTR-150B-T (Allegro ACS780 family):
- Full-scale current range: ±150 A (variant name indicates 150 A range)
- Hall-effect, galvanically isolated current sensor with a direct conduction path
- Bidirectional current sensing with analog output proportional to current (ratiometric to supply)
- High isolation between primary current path and output (suitable for protecting logic/system)
- Wide operating temperature range (typical for automotive/industrial use)
- Fast response/bandwidth for real-time monitoring
- RoHS compliant; packaging: Tape & Reel (KLRTR) for automated handling
Note: Specific supply voltage, output scale, and isolation voltage are per datasheet; this summary covers the key features typically highlighted for this variant.

Package

The ACS780KLRTR-150B-T is supplied in a 5-pin single-inline through-hole current-sensor package (SIP-5 / TO‑220‑style form factor). See Allegro's ACS780 datasheet for mechanical drawings.

Pinout

Pin count: 5 terminals.
Functions:
- IP+ (high‑current terminal) — one end of the integrated conductor for the measured current.
- IP− (high‑current terminal) — the other end of the integrated conductor.
- VCC — supply voltage for the sensor (typically 5 V).
- GND — ground/reference.
- VOUT — analog output voltage proportional to sensed current (for the "B" version it is ratiometric and centered at VCC/2 for bidirectional measurement).
