BTS 824R is a smart high-side power switch produced by Infineon Technologies AG. It has four channels, each with a status feedback of 4 x 90mΩ, an operating voltage of 5.5.40V, a switch resistance of 90mΩ and a rated load current of 4.7A. The current limitation is 12A.
The BTS824R Smart High‑Side Power Switch from Infineon provides four parallel channels (4 × 90 mΩ) for high‑current loads up to 47 A per channel. It features CMOS‑compatible inputs, low standby current, and a range of built‑in protection functions such as short‑circuit, overload, over‑voltage, reverse‑battery, and ESD protection.
The datasheet includes detailed pin definitions, maximum ratings, thermal and electrical characteristics, operating parameters, and truth tables for parallel channel operation. Package information and ordering codes are also provided for PCB integration.
| Operating voltage (Vop) | 5.5 – 40 V |
|---|---|
| On‑state resistance (Ron) | 9 mΩ typ / 22.5 mΩ max |
| Nominal load current (single channel) | 47 A |
| Standby current (input pin) | 0.3 µA |
| Maximum short‑circuit current | 12 A |
The device operates from 5.5 V up to 40 V.
It provides four independent high‑side channels.
Each channel can handle up to 47 A, with a combined 19 A when four channels are paralleled.
