TPS2815D – TEXAS INSTRUMENTS

The Texas Instruments TPS2815D is a single-channel, 40V, bidirectional, high-side current and voltage monitor in a compact 6-pin SOT-23 package. It features an integrated high-side current sense amplifier with a programmable threshold, enabling precise current monitoring up to ±2A with a typical accuracy of ±1%. The device also incorporates a voltage monitor with an independent threshold, offering comprehensive system protection. The TPS2815D operates from a wide input voltage range of 4.5V to 40V, making it suitable for a variety of applications. Its open-drain output signals provide flexible interfacing with microcontrollers for fault indication. Key advantages include its small form factor, low quiescent current (typically 150µA), and robust overvoltage and overcurrent protection features. Common use cases involve battery management systems (BMS), motor control, and power supply monitoring where accurate current and voltage measurement with compact size and low power consumption are crucial. The programmable thresholds allow for customized protection levels tailored to specific application requirements. Its bidirectional functionality is particularly advantageous in applications involving power flow in both directions.
