The TPS3899 is a nano power, precision
voltage supervisor with ±0.5% threshold accuracy and programmable sense and reset time delay
in a 6 pin space saving 1.5mm x 1.5mm WSON package. The TPS3899 is a feature-rich voltage
supervisor that offers the smallest total solution size in its class. Built-in hysteresis
along with programmable delay prevent false reset signals when monitoring a voltage rail or
push button signals.
The separate VDD and SENSE pins allow for
the redundancy sought by high-reliability systems. SENSE is decoupled from VDD and can
monitor rail voltages other than VDD. Optional use of external resistors are supported by
the high impedance input of the SENSE pin. Both CTS and CTR provide delay adjustability on
the rising and falling edges of the RESET signals. CTS also functions as a debouncer by
ignoring voltage glitches on the monitored voltage rails and operates as a "manual reset"
that can be used to force a system reset.
The precision performance, best in-class
features in a compact form factor, makes the TPS3899 an ideal solution for wide ranging
industrial and battery-powered applications such as Factory/Building Automation, Motor
Drives, and consumer products. The device is fully specified over a temperature range of
–40°C to +125°C (TA).
