... APPLICATIONS INFORMATION Voltage Monitoring The LTC2913 is a low power dual voltage monitoring circuit with two undervoltage and two overvoltage inputs. A timeout period that holds OV and UV asserted after all faults have cleared is adjustable using an external capacitor and is externally disabled. Each voltage monitor has two inputs (VHn and VLn) for detecting undervoltage and overvoltage conditions. When confi ...

... LTC2913 APPLICATIONS INFORMATION Power-Up/Power-Down As soon as V reaches 1V during power-up, the UV output CC asserts low and the OV output weakly pulls to V The LTC2913 is guaranteed to assert UV low and OV high under conditions of low V , down (2.1V maximum), the VH and VL inputs take CC control. Once both VH inputs and V ...

... Shunt Regulator ) that The LTC2913 has an internal shunt regulator. The V UOTO operates as a direct supply input for voltages up to 6V. Under this condition, the quiescent current of the device remains below a maximum of 80µA. For V ...

... If LATCH is pulled low while the timeout period is active, the OV pin latches as before. Disable (LTC2913-2) The LTC2913-2 allows disabling the UV and OV outputs via the DIS pin. Pulling DIS high will force both outputs to remain weakly pulled high, regardless of any faults that occur on the inputs. However UVLO condition occurs, UV asserts and pulls low, but the timeout function is bypassed ...
