PI5USB2546AQ USB Charging Port Controller and Load Detection Power Switch Features Description Applications Pin Configuration (TQFN-16L, ZH) PI5USB2546AQ www.diodes.com July 2018 Document Number DS41253 Rev 1-2 1 Diodes Incorporated PI5USB2546AQ Pin Description Pin Name Type Description Input voltage and supply voltage connect 0.1F or greater ceramic capacitor from IN to 1 IN P GND as close to the device as possible 2 DM OUT I/O D- Data line to USB host controller. 3 DP OUT I/O D+ data line to USB host controller. Logic-level input signal used to control the charging mode, current limit threshold, and 4 ILIM SEL I load detection, see the control truth table. Can be tied directly to IN or GND without pull-up or pull-down resistor. Logic-level input for turning the power switch and the signal switches on/off, logic low 5 EN I turns off the signal and power switches and holds OUT in discharger. Can be tied directly to IN or GND without pull-up or pull-down resistor. 6 CTL1 I Logic-level inputs used to control the charging mode and signal switches see the control 7 CTL2 I truth table. Can be tied directly to IN or GND without pull-up or pull-down resistor. 8 CTL3 I 9 O Active-low open-drain output, asserted in load detection conditions STATUS 10 DP IN I/O D+ data line to downstream connector. 11 DM IN I/O D- data line to downstream connector. 12 OUT P Power-switch output 13 O Active-low open-drain output, asserted when over-temperature or current limit conditions FAULT 14 GND G Ground connection. External resistor connection used to set the low current-limit threshold and the load 15 ILIM LO I detection current threshold. A resistor to ILIM LO is optional see Current-Limit Settings. 16 ILIM HI I External resistor connection used to set the high current-limit threshold. NA Exposed PAD G Internally connected to GND. Thermal pad to heat-sink the part to the circuit board. * I = Input O = Output P = Power G = Ground Series Charging Detection Supports Table Non- BC1.2 Charging Mode Part Number Load Detection DCP-1.2V Divider-1A Divider-2A Divider-2.4A PI5USB2546AQ PI5USB2546AQ www.diodes.com July 2018 Document Number DS41253 Rev 1-2 2 Diodes Incorporated
