Features

Description

IR2152 gate driver IC, and incorporates a high voltage

half-bridge gate driver with a front end oscillator simi-

lar to the industry standard CMOS 555 timer. The

IR21541 provides more functionality and is easier to

use than previous ICs. A shutdown feature has been

designed into the C T pin, so that both gate driver out-

puts can be disabled using a low voltage control sig-

nal. In addition, the gate driver output pulse widths are

the same once the rising undervoltage lockout thresh-

old on V CC has been reached, resulting in a more

stable profile of frequency vs time at startup. Noise im-

munity has been improved significantly, both by low-

ering the peak di/dt of the gate drivers, and by

increasing the undervoltage lockout hysteresis to 1V.

Finally, special attention has been payed to maximiz-

ing the latch immunity of the device, and providing

comprehensive ESD protection on all pins.
