11 / 31 page 11 TPS61043 www.ti.com SLVS465C – DECEMBER 2003 – REVISED FEBRUARY 2016 Product Folder Links: TPS61043 Submit Documentation Feedback Copyright © 2003–2016, Texas Instruments Incorporated Device Functional Modes (continued) 8.4.2 Undervoltage Lockout An undervoltage lockout feature prevents mis-operation of the device at input voltages below 1.5 V (typical). As long as the input voltage is below the undervoltage threshold the device remains off, with the main MOSFET switch (Q1) and the LED switch (Q2) open. 8.4.3 Thermal Shutdown An internal thermal shutdown is implemented in the TPS61043 that shuts down the device if the typical junction temperature of 160°C is exceeded. If the device is in thermal shutdown mode, the main MOSFET switch (Q1) and the LED switch (Q2) are open. |
