Pin Function
5V Supply Input: Optional system power supply connection. Required only
for 5V V_CC and V_PP output voltage.
Slot A V_CC Output: Pins 2, 22, and 24 must be externally connected
together.
Channel A V_CC and V_PP Output Monitor (Output): Low on error condition.
Serial Data (Input)
Serial Clock (Input)
System Reset (Input): Active low signal deactivates the MIC2564A, clearing
the serial registers and forcing the four power outputs to 0V (GND).
Serial Data Latch (Input)
Channel B V_CC and V_PP Output Monitor (Output): Low on error condition.
Slot B V_CC Output: Pins 11, 13, and 15 must be externally connected
together.
3.3V Supply Input: Required system power supply connection. Powers 3.3V
V_CC and V_PP outputs and all internal circuitry.
Ground
Slot B V_PP Output
12V Supply Input: Optional system power supply connection. Required only
for 12V V_PP output voltage.
