ISL55110, ISL55111

Dual, High Speed MOSFET Driver

The ISL55110 and ISL55111 are dual high speed mosfet

drivers intended for applications requiring accurate pulse

generation and buffering. Target applications include

Ultrasound, CCD Imaging, Automotive Piezoelectric

distance sensing and clock generation circuits.

With a wide output voltage range and low on resistance,

these devices can drive a variety of resistive and capacitive

loads with fast rise and fall times, allowing high speed

operation with low skew as required in large CCD array

imaging applications.

The ISL55110 and ISL55111 are compatible with 3.3V and

5V logic families and incorporate tightly controlled input

thresholds to minimize the effect of input rise time on output

pulse width. The ISL55110 has a pair of in-phase drivers

while the ISL55111 has two drivers operating in antiphase.

Both inputs of the device have independent inputs to allow

external time phasing if required.

The ISL55110 has a power down mode for low power

consumption during equipment standby times, making it

ideal for portable products.

The ISL55110 and ISL55111 are available in 16 Ld Exposed

pad QFN packaging and 8 Ld TSSOP. Both devices are

specified for operation over the full -40°C to +85°C

temperature range.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and 100%

matte tin plate termination finish, which are RoHS compliant and

compatible with both SnPb and Pb-free soldering operations. Intersil

Pb-free products are MSL classified at Pb-free peak reflow

temperatures that meet or exceed the Pb-free requirements of

IPC/JEDEC J STD-020.
