This document introduces a product called BTS 770 G, which is a quad switch driver that can be freely configured as a bridge or quad switch. The product is optimized for DC motor management applications and features ultra-low RDS ON values and very high peak current capability. It also has very low quiescent current and a space- and thermal optimized power P-DSO package. In addition, the product has various protection and diagnostic features, making it suitable for a wide range of applications.
The BTS 770G is a quad‑switch driver IC that integrates one double high‑side switch and two low‑side switches in a P‑DSO‑28‑9 package. It is optimized for DC motor management and offers configurable bridge or quad‑switch operation, low on‑resistance, and extensive protection features.
The device includes TTL/CMOS compatible inputs, internal clamp diodes, over‑temperature and over/under‑voltage lockout with hysteresis, short‑circuit detection, and open‑load detection. Pin definitions, block diagram, and application circuit details are provided for easy integration into automotive and industrial applications.
| Operating voltage | up to 40 V |
|---|---|
| High‑side switch typical Rds(on) | 165 mΩ |
| Low‑side switch typical Rds(on) | 55 mΩ |
| Switch configuration | Quad switch driver (one double high‑side, two low‑side) |
The BTS 770G can operate with a supply voltage up to 40 V.
The control inputs GH1 and GH2 are TTL/CMOS compatible Schmitt‑Trigger inputs with hysteresis.
The low‑side switches have a typical on‑resistance of 55 mΩ.
