This datasheet introduces the features of TrilithIC BTS 7740 G product, including low RDS ON, maximum peak current, static current, package type, short-circuit protection, operating voltage, status flag diagnosis, overtemperature shutdown, internal clamp diodes, external current sensing, undervoltage detection etc.
The BTS 7740 G is a triple‑switch driver integrating one high‑side and two low‑side DMOS switches in a single package. It is optimized for DC motor management, offering low on‑resistance, short‑circuit protection, over‑temperature shutdown, and UVLO detection. The device can be configured as a bridge or quad‑switch and supports PWM frequencies up to 1 kHz.
Key specifications include a typical peak current of 8 A, very low quiescent current of 5 µA, operating voltage up to 40 V, and on‑resistance values of 110 mΩ (high‑side) and 100 mΩ (low‑side). The package is a P‑DSO‑28‑14 plastic transistor single‑outline package. This manual is written in Chinese.
