Protections

Figure 35 Protection Functional Block Diagram (MA5302MS)

The internal protection control block dictates the operational modes, normal or shutdown, using the input of the

CSD pin. In shutdown mode, the controller IC turns off internal power MOSFETs.

The CSD pin provides five functions.

1. Power up delay timer

2. Self-reset timer

3. Shutdown input

4. Latched protection configuration

5. Shutdown status output (host I/F)

The CSD pin cannot be paralleled with another MA5302MS directly.

The operating statuses of the protection features are shown in Table 2.
