- 6.1 to 18V operating range
- 3.3 and 5V logic compatible
If you have a uC and you want to control some serious power with it like large motors, that typically means hooking up large power MOSFETs to its logic output pins. If you have a logic level compatible MOSFET like our STP40NF10L, you may be all set. But if you have a more typical MOSFET which has higher voltage drive requirements than the uC can provide or you need very fast switching times for efficiency, this MC34152 Dual MOSFET driver may be just what you need.
The MC34152 is a fast dual channel, non-inverting driver that is logic compatible on the input and capable of sinking or sourcing up to 1.5A on each of its outputs and can drive most power MOSFETs or multple power MOSFETs without breaking a sweat.
If you are using the MOSFET to occasionally turn something on or off, achieving maximum efficiency may not be all that important, but for fast switching in an application like DC-DC conversion or motor speed control, getting the MOSFETs through their inefficient linear region as quickly as possible can be important. The high current and fast switching capability of these devices handles large capacitive loads to ensure that happens.
If you need even more grunt, check out the MIC4422 below that can handle up to 9A peak.
To handle the fairly high transient currents during switching, the Vcc pins should be bypassed with a .1uF ceramic cap in parallel with approximately a 4.7uF tantalum across the Vcc and GND pins as closely as possible.
It is packaged in a DIP-8 package for easy prototype use.
- Datasheet strongly suggests not using solderless breadboard construction with this device in order to avoid excess output ringing and overshoot which can damage the device or cause erratic behavior. Projects are best built on PCB breadboards.
