7.1 Application Information

The TPS4141-Q1 is a high-voltage, precision matched resistor divider with an integrated programmable-gain amplifier. The TPS4141-Q1 also integrates a high-voltage switch to allow for connecting or disconnecting the high-voltage sense pin (HV) and provides uni-directional current blocking when disconnected. Intended applications include, but not limited to, are high-voltage monitoring in solar panels, electric vehicle (EV) chargers, EV battery management systems (BMS), and energy storage systems (ESS). The device is designed for automotive and industrial applications where accurate, high-voltage measurements are required.

The TPS4141-Q1 supports an input voltage range of 4.5V to 20V on the supply pin and a logic high of 2.4V to 20V on the CE, DIV0, and DIV1 pins. The TPS4141-Q1 supports up to 1200V uni-directional voltage sensing and up to ±1200V bi-directional voltage sensing when an external reference voltage is supplied on REF.
