The device uses an N-channel MOSFET for low resistance, maintaining voltage regulation to the load. It is designed for applications where short circuits or heavy capacitive loads are encountered. Device features include enable, reverse blocking when disabled, output discharge pulldown, overcurrent protection, overtemperature protection, and deglitched fault reporting. 8.2 Functional Block Diagram Figure 19. TPS2001D Block Diagram 8.3 Feature Description 8.3.1 Undervoltage Lockout The undervoltage lockout (UVLO) circuit disables the power switch until the input voltage reaches the UVLO turn- on threshold. Built-in hysteresis prevents unwanted ON/OFF cycling due to input voltage drop from large current surges. FLT is high impedance when the TPS2001D is in UVLO. 8.3.2 Enable The logic enable input (EN), controls the power switch, bias for the charge pump, driver, and other circuits. The supply current is reduced to less than 1 µA when the TPS2001D is disabled. Disabling the TPS2001D immediately clears an active FLT indication. The enable input is compatible with both TTL and CMOS logic levels. The turnon and turnoff times (tON, tOFF) are composed of a delay and a rise or fall time (tR, tF). The delay times are internally controlled. The rise time is controlled by both the TPS2001D and the external loading (especially capacitance). Its fall time is controlled by the loading (R and C), and the output discharge (RPD). An output load consisting of only a resistor experiences a fall time set by the device. An output load with parallel R and C elements experiences a fall time determined by the (R × C) time constant if it is longer than the tF. The enable must not be left open, and may be tied to VIN or GND depending on the device. |
