TPS3899-Q1 Nano-Power, Precision Voltage Supervisor, Push-Button Monitor with
Programmable Sense and Reset Delay
1 Features
3 Description
Qualified for automotive applications:
The TPS3899-Q1 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 1.5 mm × 1.5 mm WSON package. The
TPS3899-Q1 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.
•
AEC-Q100 qualified with the following results:
– Device temperature grade 1: –40°C to +125°C
ambient operating temperature
– Device HBM ESD classification level 2
– Device CDM ESD classification level C7B
Designed for high performance:
•
•
•
Nano quiescent current: 125 nA (Typ)
High threshold accuracy: ±0.5% (Typ)
Built-in precision hysteresis (VHYS): 5% (Typ)
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.
Designed for a wide range of applications:
•
Operating voltage range:
– 0.85 V to 6 V (DL and PL outputs)
– 1 V to 6 V (PH output)
•
•
•
•
Adjustable threshold voltage: 0.505 V (Typ)
Precision voltage and push-button monitor
Programmable sense and reset delay
Fixed (VIT-) voltage: 0.8 V to 5.4 V in 0.1 V steps
The precision performance, best in-class features in
a compact form factor, makes the TPS3899-Q1 an
ideal solution for wide ranging automotive and battery-
powered / low-power applications. The device is fully
specified over a temperature range of
Multiple output topologies / Package type:
•
