IS31FL3236 Typical Application
Figure 1 Typical Application Circuit
Note 1: The maximum global output current is set up to 23mA when REXT = 3.3k Ω . The maximum global output current can be set by external resistor, R EXT . Please refer to the detail information in Page 11.
Note 2: The IC should be placed far away from the mobile antenna in order to prevent the EMI.
