TLV841 is a nano power, precision voltage supervisor with ±0.5% threshold accuracy in an ultra-small DSBGA package. The TLV841 offers three pinout variants (S, M, C) to provide many unique options in the smallest package size. Built-in hysteresis along with fixed or programmable (TLV841C) reset delay prevent false reset signals when monitoring a voltage rail or push button signals. The separate VDD and SENSE (TLV841S) pins allow for the redundancy sought by high-reliability systems. SENSE is decoupled from VDD and can monitor rail voltages other than VDD or can be used as a push-button input. TLV841M offers a separate manual reset (MR) pin to force a reset condition with an external signal or be used as a push button input. TLV841M can be setup for VDD and MR pin monitoring to create a simple two-channel supervisor.

TLV841 offers precision performance, low power consumption, and best in-class features in the smallest compact form factor is focused for wide range battery powered applications such as personal and consumer products. Optional use of external resistors are supported by the high impedance input of the SENSE pin. TLV841S offers fixed reset delay timing options with no need of an external capacitor. TLV841C allows programmable reset time delay including a minimum delay when the CT pin is left floating. TLV841 operates over a temperature range of -40°C to +125°C (TA).
