Introduction
TPS2044BDR is part of the Power Management Integrated Circuits (PMICs) category, specifying in power distribution switches and load drivers, designed for optimal power management within electronics.
Product Features and Performance
Four independently controlled output channels.
High-side N-Channel MOSFET output configuration.
Integrated fault protection with current limiting (fixed), over-temperature protection, and under-voltage lockout (UVLO).
Interface for simple on/off control.
Supports a wide range of load voltages from 2.7V to 5.5V.
Product Advantages
Offers multi-channel output in a single IC for space and cost efficiency.
Provides robust protection against over-current and thermal runaway, enhancing system reliability.
The low Rds(on) (70mOhm typically) minimizes power loss and improves efficiency.
Flexible power supply operation not requiring specific Vcc/Vdd.
