9.3.5 Current Limiting

A current-limiting sense amplifier is provided in the SGx524 device. The current-limiting sense amplifier exhibits a threshold of 200 mV ±25 mV and must be applied in the ground line since the voltage range of the inputs is limited to 1 V to –1 V. Caution should be taken to ensure the –1-V limit is not exceeded by either input, otherwise, damage to the device may result.

Foldback current limiting can be provided with the network shown in Figure 9-1. The current-limit schematic is shown in Figure 9-2.
