TPS2042A Description

Short technical summary and product information.

The Texas Instruments TPS2042A is a 2-channel, high-side MOSFET power switch designed for power distribution systems. It is suitable for applications where heavy capacitive loads and short circuits are anticipated.

 

Each switch in the TPS2042A can handle 500 mA of continuous current per channel with a fixed current limit of 1A. The device operates over an input voltage range of 2.7V to 5.5V and features an 80mΩ on-resistance. The enable inputs are CMOS- and TTL-compatible and operate in an active-low configuration.

 

Key features include independent thermal and short-circuit protection for each channel, a typical rise time of 2.5 ms, and undervoltage lockout. The standby supply current is a maximum of 10 uA for dual-channel devices. The operating temperature range is from 0°C to 125°C.

 

The TPS2042A is available in an 8-pin SOIC package with dimensions of 4.9 mm x 6 mm, offering a compact solution for power management needs.
