SELF-OSCILLATING HALF-BRIDGE DRIVER

IR2153(D)(S) &(PbF)
Description
porates a high voltage half-bridge gate driver with a front end oscillator similar to the industry standard CMOS 555 timer. The IR2153 provides more functionality and is easier to u than previous ICs. A shutdown feature has been designed into the C T pin, so that both gate driver outputs can be disabled using a low voltage control signal. In addition, the gate driver output pul w
idths are the same once the rising undervoltage lockout threshold on V CC has been reached, resulting in a more stable profile of frequency vs time at startup.Noi immunity has been improved significantly, both by lowering the peak di/dt of the gate drivers, and by increasing the undervoltage lockout hysteresis to 1V . Finally, special attention has been payed to maximizing the latch immunity of the device, and providing comprehensive ESD protection on all pins.

Note 1:
This IC contains a zener clamp structure between the chip V CC and COM which has a nominal bre
akdown voltage of 15.6V. Plea note that this supply pin should not be driven by a DC, low impedance power source greater than the V CLAMP specified in the Electrical Characteristics ction.
Note 2:Care should be taken to avoid output switching conditions where the V S node flies inductively below ground by more than 5V.
Note 3:
Enough current should be supplied to the V CC pin of the IC to keep the internal 15.6V zener diode clamping the voltage at this pin.
Recommended Operating Conditions
For proper operation the device should be ud within the recommended conditions.

Absolute Maximum Ratings
培育近义词Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage param-eters are absolute voltages referenced to COM, all currents are defined positive in
to any lead. The thermal resistance and power dissipation ratings are measured under board mounted and still air conditions.
