SGM42544中文资料Quad Half-Bridge Driver IC数据手册SGMICRO规格书

描述 Description

The SGM42544 provides four half-bridge drivers, each channel is controlled by separate individually controllable input. It is suitable for driving inductive loads, including four solenoids, relays, DC motors or other loads. The device allows operation with single or bipolar power supplies (such as ±20V).
With proper heatsinking, the SGM42544 can deliver up to 2A peak output current per channel (at TJ = +25℃). Paralleling the outputs is possible for higher current applications.
Protection features include under-voltage lockout, over-current, short-circuit and thermal shutdown. Fault conditions are indicated on the nFAULT pin.
The SGM42544 is available in a Green TSSOP-28 (Exposed Pad) package.
