TPS4141-Q1 概述
A high-voltage precision resistor divider is a specialized analog front-end IC that scales high-voltage inputs down to a safe range for downstream ADC or microcontroller measurement. It combines matched precision resistors with a PGA to maintain accuracy across temperature and voltage extremes, eliminating the need for discrete resistor networks and trimming. This architecture reduces board area and improves measurement reliability in high-voltage environments.
The TPS4141-Q1 integrates a high-voltage switch that connects or disconnects the high-voltage sense pin, providing uni-directional current blocking when disconnected. The programmable-gain amplifier supports four divider ratios using DIV0 and DIV1, enabling flexible measurement scaling for different voltage ranges. External precision reference voltage can be supplied from REF to HVGND for bi-directional voltage measurement, and switching between uni-directional and bi-directional sensing during operation is possible.
The device is AEC-Q100 qualified for automotive applications, ensuring robust performance over a wide temperature range. Its high-voltage capability and integrated switch make it suitable for battery management systems, traction inverters, and industrial motor drives where precise voltage monitoring is critical. The integrated PGA and matched resistors provide high accuracy, reducing system calibration overhead.
Typical applications include electric vehicle battery pack voltage monitoring, solar inverter DC bus sensing, and industrial 24V/48V system voltage measurement. The high-voltage switch allows the sense line to be disconnected for safety or power saving, while the divider ratios allow the same device to serve multiple voltage ranges. Designers should ensure proper PCB clearance and creepage distances for 1200V operation, and use the external REF for bi-directional measurements when needed.

Industrial Motor Drive Voltage Monitoring
In industrial motor drives, the DC bus voltage must be monitored for overvoltage and undervoltage protection. The TPS4141-Q1 handles voltages up to 1200V, covering common 400V and 690V drive systems. Its programmable-gain amplifier offers four divider ratios, enabling the same device to be used across multiple drive ratings. The bi-directional measurement capability supports negative bus monitoring in regenerative drives. The device's high CMRR and low noise reduce false trips, and its small SOIC-11 footprint saves board space.

设计说明
For 1200V operation, maintain sufficient spacing between the high-voltage pin and low-voltage components. Follow IPC-2221 for creepage distances. Place the REF capacitor close to the REF pin for stable reference. Use a minimum isolation barrier of 6mm for 1200V DC per common safety standards.
Pins 9 and 10 have a known discrepancy between NC and HV on the EVM; verify with the datasheet before layout. Also ensure the external reference is grounded to HVGND for bi-directional measurement. Missing this connection can cause abnormal readings.
The device dissipates little power, but ensure the SOIC-11 package has adequate copper pour for heat spreading. At high ambient temperatures, verify the junction temperature stays within datasheet limits. Keep the high-voltage traces away from the REF pin to reduce thermal and electrical interference.
