Data sheet:
TPS371K-Q1 is an automotive supervisor for voltage monitoring with an integrated buffer for 400V and 800V DC-link voltage measurements. The TPS371K-Q1 eliminates large resistor ladders with the integrated high voltage ladder. This device’s SENSE pin can be directly connected to 400V or 800V automotive battery systems and DC-Link for continuous monitoring of overvoltage (OV), undervoltage (UV), and low undervoltage (LUV) conditions. The TPS371K-Q1 offers CTS for programmable glitch rejection for noisy environments.
The TPS371K-Q1 has a integrated high-speed buffer VSENSE for supply voltage measurements. The buffer has a low output impedance which can directly drive ADC inputs. VSENSE is a scaled down voltage of the SENSE pin input.
The combination of voltage supervisor and integrated buffer allows for the smallest signal chain size for direct monitoring of 400V and 800V systems. This combination also allows for redundant digital and analog always on voltage fault monitoring.
The TPS371K-Q1 is available in a 12.8mm × 7.4mm SOIC 15-pin package. TPS371K-Q1 operates over -40°C to +125°C TA.
- AEC-Q100 qualified for automotive applications
- Device temperature grade 1: –40°C to +125°C
- Functional Safety-Compliant Targeted (Preview)
- Development targeted for functional safety applications
- Documentation to aid ISO 26262 system design
- Overvoltage and undervoltage fault monitor for 400V & 800V BMS and DC-Link
- 1% overvoltage and undervoltage outputs
- Fast detection time (<5µs) to help minimize system fault tolerant time interval
- 30V to 60V Low UV output
- Device flexibility to meet design requirements
- User selectable adjustable overvoltage and undervoltage thresholds
- User programmable capacitor-based glitch rejection and deassertion delay
- Integrated buffer for ADC monitoring
- High accuracy 0.35% (maximum) scaled down voltage of sense pin
- VSENSE pin can directly drive high-speed ADC inputs
- Designed for safety applications (Preview)
- Output latching feature to help bring system to safe state
- Built-In Self-Test to monitor device functionality and enhance system protection
