This diagram shows a typical dual hot-swap application. The pullup resistors at PWRGD1, PWRGD2 and FAULT
should be relatively large (e.g., 100 k
) to reduce power loss unless they are required to drive a large load.
Figure 27. Typical Dual Hot-Swap Application
A 0.1-
F ceramic capacitor in parallel with a 1-F ceramic capacitor should be placed on the input power
terminals near the connector on the hot-plug board to help stabilize the voltage rails on the cards. The
TPS2300/01 does not need to be mounted near the connector or these input capacitors. For applications with
more severe power environments, a 2.2-
F or higher ceramic capacitor is recommended near the input
terminals of the hot-plug board. A bypass capacitor for IN1 and for IN2 should be placed close to the device.
A 0.1-
F ceramic capacitor is recommended per load on the TPS2300/01; these capacitors should be placed
close to the external FETs and to TPS2300/01. A larger bulk capacitor is also recommended on the load. The
value of the bulk capacitor should be selected based on the power requirements and the transients generated by
the application.
To deliver power from the input sources to the loads, each channel needs an external N-channel MOSFET. A
few widely used MOSFETs are shown in Table 3. But many other MOSFETs in the market can also be used
with TPS23xx in hot-swap systems.
