SEC S248 Hall Switch Datasheet
The S248 is a full‑polarity Hall‑effect sensor built with mixed‑signal CMOS technology. It uses a chopping‑stabilized amplifier and an embedded clock to periodically put high‑current circuits into a low‑power sleep mode, extending battery life. When a magnetic field exceeds the set threshold, the output transistor switches to the open (Bop) state; otherwise it stays closed (Brp).\n\nTypical applications include solid‑state switches, cordless‑phone reminder switches, and flip‑cover mobile phone power switches. The device is offered in 3‑pin SOT‑23 and 3‑pin SIP (TO‑92) packages with detailed pinout and mechanical drawings provided. This manual is written in Chinese.
