The TPS2091DR has a maximum current limit of 1.5A per channel, but it's recommended to limit the current to 1.2A per channel for optimal performance and thermal considerations.
The enable pins (EN1 and EN2) are active-low inputs. Connect them to a logic low (GND) to enable the corresponding channel, and connect them to a logic high (VCC) to disable the channel.
The FLAG output is an open-drain output that indicates an overcurrent or undervoltage condition on either channel. It can be used to alert the system to a fault condition and take appropriate action.
The TPS2091DR has a built-in thermal shutdown feature that disables the device when the junction temperature exceeds 150°C. To handle thermal shutdown, ensure proper heat sinking, reduce the current limit, or implement a thermal monitoring and shutdown scheme in your system.
Yes, the TPS2091DR is suitable for hot-swapping applications due to its fast turn-on and turn-off times, as well as its ability to handle inrush currents. However, ensure that your system design takes into account the device's power-on reset and fault detection features.
