MC34152PG

MC34152PG Description

The MC34152PG from onsemi is a dual-channel, low-side gate driver IC designed for high-performance switching applications. Housed in an 8-pin DIP (Through Hole) package, this obsolete but robust component operates within a 6.1V to 18V supply range, making it suitable for a variety of power electronics designs. With a peak output current of 1.5A (source/sink), it ensures efficient driving of MOSFETs and IGBTs, while its fast rise/fall times (36ns/32ns, typical) minimize switching losses. The IC features independent channels, allowing flexible control of two separate loads, and is rated for 0°C to 150°C junction temperatures (TJ), ensuring reliability in demanding environments.
