SBVS286 – MARCH 2017 TPS3851-Q1 High-Accuracy Voltage Supervisor with Integrated Watchdog Timer
1 Features 3 Description The TPS3851-Q1 device combines a precision
voltage supervisor with a programmable watchdog
timer. The TPS3851-Q1 comparator achieves a 0.8%
accuracy (–40°C to +125°C) for the undervoltage
(VITN) threshold. The TPS3851-Q1 also includes
accurate hysteresis on the undervoltage threshold
making the device ideal for use with tight tolerance
systems. The supervisor RESET delay features a
15% accuracy, high-precision delay timing. 1 AEC-Q100 Qualified with the Following Results:
– Device Temperature Grade 1: –40°C to 125°C
Ambient Operating Temperature Range
– Device HBM ESD Classification Level 2
– Device CDM ESD Classification Level C4B
Input Voltage Range: VDD = 1.6 V to 6.5 V
1% Voltage Threshold Accuracy
Low Supply Current: IDD = 10 ВµA (typ) …
