This document describes the features and characteristics of TrilithIC BTS 774 G, including the ability to be configured as a bridge or quad-switch, ultra-low RDS ON, high peak current capability, low quiescent current, full short-circuit protection, overtemperature shut down, etc.
The BTS 774G is a Trilithic™ quad switch driver IC that integrates one high‑side and two low‑side MOSFET switches in a compact P‑DSO‑28‑9 package. It is designed for DC motor management and offers ultra‑low on‑resistance, high peak current capability, and extensive protection functions.
Key features include CMOS‑compatible inputs, internal clamp diodes, over‑ and under‑voltage lockout, overtemperature shutdown, short‑circuit detection, and open‑load detection. The device can be configured as a bridge, H‑bridge, or other switch topologies and supports current‑sense resistor addition for automotive and industrial applications.
| Typical high‑side on‑resistance (Rds(on)) | 165 mΩ |
|---|---|
| Typical low‑side on‑resistance (Rds(on)) | 45 mΩ |
| Maximum operating voltage | 40 V |
| Number of integrated switches | 1 high‑side + 2 low‑side (total 3) |
The high‑side switch has a typical on‑resistance of 165 mΩ at 25 °C.
The device contains one high‑side switch and two low‑side switches.
It provides full short‑circuit protection, over‑temperature shutdown, over‑ and under‑voltage lockout, and open‑load detection.
The BTS 774G operates up to 40 V.
