MAX5915 Evaluation Kit
General Description
The MAX5915 evaluation kit (EV kit) is a fully assembled
and tested surface-mount dual hot-swap controller cir-
cuit board for two PCI 2.2 server line cards. The circuit
uses a MAX5915 IC in a 28-pin TSSOP package. The
EV kit provides independent power control for the
+3.3V, +5V, 鹵12V, and +3.3V auxiliary outputs to the
PCI 2.2 connectors (A/B channels). The EV kit demon-
strates the MAX5915 IC鈥檚 overcurrent shutdown, output
undervoltage monitoring, power-on reset (POR), and
fault-reporting capabilities for channels A and B.
The MAX5915 IC controls the two separate external N-
channel MOSFETs for the +5V and +3.3V outputs,
respectively. The MAX5915 has internal MOSFETs that
control the 鹵12V and +3.3V auxiliary outputs of both
channels. Isolation switches are provided for both
channels鈥?+3.3V and +3.3V auxiliary supplies and to
enable/disable both channels independently.
The EV kit can also be configured to demonstrate a
dual hot-swap design without using the PCI 3.3V/64-bit
and 5V/64-bit PCI connectors.
