Overview
uP7534 Current-Limited, Power Distribution Switches General Description The uP7534 is a current limited high-side switch designed for applications where heavy capacitive loads and shortcircuits are likely to be met.
This device operates with inputs from 2.
7V to 5.
5V for both 3V and 5V systems.
Its low quiescent current (25uA) and standby current (<1uA) conserve battery power in portable.
The power switch is controlled by a logic enable input and driven by an internal charge pump circuit.
When the output load exceeds the current-limit threshold or a short is present, the uP7534 asserts overcurrent protection and limits the output current to a safe level by driving the power switch into saturation mode.
The uP7534 features glitch-blank fault flag that is asserted by overcurrent, overtemperature, or input undervoltage lockout.
The 8ms glitch-blanking time allows momentary faults to be ignored, thus preventing false alarms to the host system.
Other features include soft-start to limit inrush current during plug-in, thermal shutdown to prevent catastrophic switch failure from high-current loads, under-voltage lockout (UVLO) to ensure that the device remains off unless there is a valid input voltage present.
The uP7534 is available in SOP-8 , SOT23-5, MSOP-8, and PMSOP-8 packages.
