10 / 13 page TECHNICAL INFORMATION 10 TA1101B, Rev. 2.2, 08.17.00 Sleep Pin The SLEEP pin is a 5V logic input that when pulled high (>3.5V) puts the part into a low quiescent current mode. This pin is internally clamped by a zener diode to approximately 6V thus allowing the pin to be pulled up through a large valued resistor (1M Ω recommended) to V DD. To disable SLEEP mode, the sleep pin should be grounded. Fault Pin The FAULT pin is a 5V logic output that indicates various fault conditions within the device. These conditions include: low supply voltage, low charge pump voltage, low 5V regulator voltage, over current at any output, and junction temperature greater than approximately 155 °C. All faults except overcurrent all reset upon removal of the condition. The FAULT output is capable of directly driving an LED through a series 200 Ω resistor. If the FAULT pin is connected directly to the MUTE input an automatic reset will occur in the event of an over-current condition. Power Dissipation Derating For operating at ambient temperatures above 25 °C the device must be derated based on a 150°C maximum junction temperature, TJMAX as given by the following equation: JA A JMAX DISS ) T T ( P θ − = Where θ JA of the package is determined from the following graph: In the above graph Copper Area is the size of the copper pad on the PC board to which the heat slug of the TA1101B is soldered. The heat slug must be soldered to the PCB to increase the maximum power dissipation capability of the TA1101B package. Soldering will minimize the likelihood of an over- temperature fault occurring during continuous heavy load conditions. The vias used for connecting the heatslug to the copper area on the PCB should be 0.013” diameter.
