Texas Instruments TLV841 Nanopower Supervisor is a 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 its class’s smaller than total solution 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. On active-low outputs of TLV841S, increasing the voltage threshold hysteresis can be achieved by adding an external resistor between the SENSE and RESET pins. TLV841, with its precision performance, low power consumption, and small compact form factor, offers an ideal solution for a wide range of battery-powered applications such as personal and consumer products.
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. Optional use of external resistors is supported by the high impedance input of the SENSE pin. TLV841S offers fixed reset delay timing options with no need for an external capacitor. TLV841C allows programmable reset time delay, including a minimum delay when the CT pin is left floating. 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 set up for VDD and MR pin monitoring to create a simple two-channel supervisor solution. Texas Instruments TLV841 operates over a temperature range of -40°C to +125°C (TA).
