ANT: 300mA maximum output current, 0.5V voltage difference between input and output. Two VDD 5V-linked high side switch systems SW5V: 200mA maximum output current, 0.2V voltage difference between input and output. ACC (accessory voltage detection output): 100mA maximum output current, 0.2V voltage difference between input and output. Overcurrent protection function Overheat protection function, typ 175ºC On-chip accessory voltage detection circuit P-channel LDMOS used for power output block (Warning) The protector functions only improve the IC’s tolerance and they do not guarantee the safety of the IC if used under the conditions out of safety range or ratings. Use of the IC such as use under overcurrent protection range or thermal shutdown state may degrade the IC’s reliability and eventually damage the IC.
