Product Summary
The OZ9939GN is a Smart Multi-DIMM Selector. The OZ9939GN supports the switching between a primary SMBus and 3 other secondary SMBus. This function is particularly useful for DIMM devices and the support of PAS (Preboot Authentication Service). In addition, the OZ9939GN can be configured to support two different power planes with different sets of General Purpose Input/Output (GPIO) signals, which supplements and enhances the power management capability of the chipsets, commonly found in an ACPI (Advanced Configuration of Power Interface) subsystem.
Parametrics
OZ9939GN absolute maximum ratings: (1)VCC, DC Power Supply Voltage: -0.3 to 5.5 V; (2)VIN, VOUT DC Input, Output Voltage: -0.3 to VCC + 0.3 V; (3)IIN, DC Current Drain VCC and VCC Pins: ±25 mA; (4)TSTG, Storage Temperature: -40 to +125℃; (5)TOPER,| Operation Temperature: 0 to 70℃.
Features
OZ9939GN features: (1)SMBus 1.0 Compliant; (2)Support Pentium class and x86-based designs; (3)PMU, GPIO, and Alternative PMU modes; (4)WAKE output and Suspend Status input operates synchronously with PMU in notebook chipsets; (5)LOW power-saving Suspend mode; (6)Hardware Debounced Wakeup/Suspend input as pushbutton; (7)4 Power Control programmable outputs with builtin Power Sequencing at 10 ms to 1 second programmable intervals; (8)Optional Wakeup-Disable inputs; (9)Optional Power-On inputs.
