The OHN3075U and OHS3075U are Hallogic® bipolar Hall‑effect sensors designed for brushless DC motor applications. They operate over a broad supply voltage range (4.5 V‑24 V) and can drive more than seven TTL loads, making them suitable for harsh environments.
Key specifications include a supply‑voltage rating of 25 V, operating temperature ranges of –20 °C to +85 °C (OHN3075U) and –40 °C to +150 °C (OHS3075U), an output ON current of 25 mA, and magnetic operate points from 50 Gauss to 250 Gauss.
| Operating Temperature Range (OHN3075U) | -20 °C to +85 °C |
|---|---|
| Operating Temperature Range (OHS3075U) | -40 °C to +150 °C |
| Magnetic Operate Point (Bop) | 50 Gauss – 250 Gauss |
| Drive Capability | Up to 7 TTL loads |
They operate with supply voltages from 4.5 V to 24 V, and the absolute maximum rating is 25 V.
The sensor can drive up to seven TTL loads (or more) directly.
OHN3075U operates from –20 °C to +85 °C, while OHS3075U operates from –40 °C to +150 °C.
