Absolute Maximum Ratings
Stress beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
These are stress ratings only and functional operation of the device at these conditions are not implied. All
voltages are absolute voltages referenced to GND. Thermal resistance and power dissipation are measured under
board mounted and still air conditions.

Application Information and Additional Details
State Diagram
IR1167(A,B)S
UVLO/Sleep Mode
The IC remains in the UVLO condition until the voltage on the VCC pin exceeds the VCC turn on threshold voltage, VCC
ON. During the time the IC remains in the UVLO state, the gate drive circuit is inactive and the IC draws a quiescent
current of ICC START. The UVLO mode is accessible from any other state of operation whenever the IC supply voltage
condition of VCC < VCC UVLO occurs.
The sleep mode is initiated by pulling the EN pin below 2.5V (typ). In this mode the IC is essentially shut down and
draws a very low quiescent supply current.
Normal Mode
The IC enters in normal operating mode once the UVLO voltage has been exceeded. At this point the gate driver is
operating and the IC will draw a maximum of ICC from the supply voltage source.
