descriptionThe TPS2044 and TPS2054 quad power-
distribution switches are intended for applications
where heavy capacitive loads and short circuits
are likely to be encountered. The TPS2044 and the TPS2054 incorporate in single packages four 135-mΩ
N-channel MOSFET high-side power switches for power-distribution systems that require multiple power
switches. Each switch is controlled by a logic enable that is compatible with 5-V logic and 3-V logic. Gate drive
is provided by an internal charge pump that controls the power-switch rise times and fall times to minimize
current surges during switching. The charge pump, requiring no external components, allows operation from
supplies as low as 2.7 V.
When the output load exceeds the current-limit threshold or a short is present, the TPS2044 and TPS2054 limit
the output current to a safe level by switching into a constant-current mode, pulling the overcurrent (OCx) logic
output low. When continuous heavy overloads and short circuits increase the power dissipation in the switch
causing the junction temperature to rise, a thermal protection circuit shuts off the switch to prevent damage.
Recovery from a thermal shutdown is automatic once the device has cooled sufficiently. Internal circuitry
ensures the switch remains off until valid input voltage is present.
The TPS2044 and TPS2054 are designed to limit at 0.9-A load. These power-distribution switches are available
in 16-pin small-outline integrated-circuit (SOIC) packages and operate over an ambient temperature range of
–40°C to 85°C.
AVAILABLE OPTIONS†The D package is available taped and reeled. Add an R suffix to device type (e.g., TPS2044DR)
