Notes:
7. Specification for packaged product only.
8. Measurement is from the 50% point of the SLA rising edge.
9. Output enabled into short circuit.
10. Measurement is from the Hi-Z- or 0V-state command to the beginning of the slope. Measurement does not apply when device is in current limit or
thermal shutdown.
11. V
CC3
IN powers all internal logic, bias, and drive circuitry, and is required for operation.
12. V
PP
and V
CC5
IN are not required for operation.
13. V
PP
IN must be either high-impedance or greater than or approximately equal to the highest voltage V
CC
in the system. For example, if both 3.3V
and 5V are connected to the MIC2564A, V
PP
IN must be either 5V, 12V, or high-impedance.
