14-HTSSOP exposed-pad package — thermal and footprint demands
The TPS2013APWP: The 1:1 input-to-output ratio and single N-channel output mean the layout is straightforward — the high-side switch sits between the supply rail and the load, with the exposed pad tied to the system ground plane for heat sinking. The 33 mOhm typical Rds(on) at 5 V gate drive keeps conduction losses under 75 mW at 1.5 A, so the thermal pad is sized for ambient dissipation, not forced airflow.
1.5 A continuous output with fixed current limiting
Rated for 1.5 A maximum continuous output, the TPS2013APWP integrates fixed current limiting, over-temperature shutdown, and undervoltage lockout (UVLO) on the load supply. The current limit is non-adjustable — the part trips at a factory-set threshold above 1.5 A, making it a fit for loads that draw a steady current below that ceiling without inrush exceeding the limit. The On/Off interface is non-inverting and does not require a Vcc/Vdd bias supply — the enable pin is referenced to the load voltage rail. This simplifies the control logic: a logic-high on the input turns the N-channel FET on, and the output follows the input with no external gate-drive components.
