Number Name
Type Description
D6 LDO1P8 O 1.8V LDO for Internal Core (always On when Vrect is powered). Connect a capacitor to ground. E1,E2,E3, E5,E6 VOUT O Main LDO output pin. Connect a capacitor to ground. E4 OUT_S I Input current positive input when operating in Tx mode with external current sense resistor. If external current sense resistor is not used, connect this pin to VOUT pins. F1, F2, F3, F4, F5, F6 VRECT O Filter cap for the internal rectifier output. Connect a capacitor to ground. G1 BST1 O Bootstrap capacitor for driving high side N-MOSFET of the internal rectifier. Connect a capacitor from AC1 to BST1. G2, H1, H2, H3 AC1 I/O AC1 power input. Connect to RX LC tank (due to symmetry may connect to Rx coil or Resonance Capacitor). Active-low enable pin. When it is pulled-up High by the AP GPIO, the rectifier will be set in Diode mode without G3 nEN I ASK signal modulation. While it is pulled-down Low, the rectifier can be set in any predefined modes. G5, H4, H5, H6 AC2 I/O AC2 power input. Connect to RX LC tank (due to symmetry may connect to Rx coil or Resonance Capacitor). G4 DEMOD I Tx mode Communication Demodulator input. Connect to LC node via diode and DEMOD filter. G6 BST2 O Bootstrap capacitor for driving the high side N-MOSFET of the internal rectifier. Connect a capacitor from AC2 to BST2. C1, C2, C6, J1, J2, J3, J4, PGND GND Power Ground. All PGND pins must be connected together externally. J5, J6 Note - ‘I’ = Input (Digital or Analog), ‘O’ = Output (Digital). © 2019 IDT A Renesas Company. 4 Revision 0.8 August 29, 2019
