The TPS4141-Q1 is a high-voltage monitoring device designed for automotive and industrial applications. The TPS4141-Q1 compactly integrates a precision matched, thin-film SiCr resistor divider with a programmable-gain amplifier for sensing system voltages that require accurate measurement in the range of -1kV:1kV. The High-Voltage (HV) sense pin of the device can be seamlessly connected and disconnected from the broader system using the integrated high-voltage switches which also provide uni-directional current blocking when disconnected. With a nominal HV to GND resistance of 30MΩ, TPS4141-Q1 enables power efficient HV sensing that is optimized for a wide range of analog to digital converter full scale voltages through the programmable gain settings of the amplifier, selectable via the DIV0 and DIV1 pins.
The TPS4141Q1EVM helps designers evaluate the operation and performance of the TPS4141-Q1. The TPS4141-Q1 is a compact, -1kV:1kV high-voltage monitor. The inputs and output connections to the board are terminal blocks, which allow for easily wired connections. The TPS4141Q1EVM contains multiple test points for monitoring the TPS4141-Q1 functionality. This user's guide provides the connectors, test point descriptions, operational modes, schematic, bill of materials, and board layout of the EVM.
