BTS 7810 K is part of the TrilithIC family and contains one double high-side switch and two low-side switches. It features configurable bridge or quad-switch mode and is optimized for DC motor management applications. The key features include low RDS ON, maximum peak current, very low quiescent current, small outline, status flag for over temperature, open load detection, overtemperature shut down, etc.
The BTS 7810 K is a quad D‑MOS switch from Infineon's TrilithIC family, featuring one double high‑side switch and two low‑side switches that can be configured as a bridge or independent switches. It offers low on‑resistance, high current capability, and integrated protection functions such as load short‑circuit protection, over‑temperature shutdown, open‑load detection, and undervoltage lockout.
The datasheet details pin configuration and definitions, a functional block diagram, and circuit operation. Electrical characteristics include absolute maximum ratings, operating ranges, and typical performance values such as peak current, on‑resistance, quiescent current, and supply voltage limits.
| Maximum peak current | 42 A (typ) @ 25 °C |
|---|---|
| Rds(on) high-side | 26 mΩ (typ) @ 25 °C |
| Rds(on) low-side | 14 mΩ (typ) @ 25 °C |
| Quiescent current | 4 µA (typ) @ 25 °C |
| Operating voltage | Up to 40 V |
| Supply voltage rating (Vs) | 42 V |
| High‑side input voltage (HS Vu) | 15 V |
| Low‑side input voltage (LS Vi) | 20 V |
| Status output current | 2 mA (typ) |
The typical maximum peak current is 42 A at 25 °C.
Typical Rds(on) is 26 mΩ for the high‑side switch and 14 mΩ for the low‑side switches at 25 °C.
It contains one double high‑side switch and two low‑side switches, forming a quad D‑MOS switch.
