10 / 12 page LTC2913 10 2913fa TYPICAL APPLICATIONS APPLICATIONS INFORMATION where RPD is the on-resistance of the internal pull-down transistor, typically 50Ω at VCC > 1V and at room tem- perature (25°C). CLOAD is the external load capacitance on the pin. Assuming a 150pF load capacitance, the fall time is 16.5ns. The rise time on the UV and OV pins is limited by a 400k pull-up resistance to VCC. A similar formula estimates the output rise time (10% to 90%) at the UV and OV pins: tRISE ≈ 2.2 • RPU • CLOAD where RPU is the pull-up resistance. OV Latch (LTC2913-1) With the LATCH pin held low, the OV pin latches low when an OV condition is detected. The latch is cleared by raising the LATCH pin high. If an OV condition clears while LATCH is held high, the latch is bypassed and the OV pin behaves the same as the UV pin with a similar timeout period at the output. 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, if a UVLO condition occurs, UV asserts and pulls low, but the timeout function is bypassed. UV pulls high as soon as the UVLO condition is cleared. DIS has a weak 2µA (typical) internal pull-down current guaranteeing normal operation with the pin left open.
