(1) There will be 0-ns of deglitch for PWRx. (2) There will be 62.52-µs of deglitch for VCOM_CTRL. (3) There will be 93.75-µs of deglitch for WAKEUP. PWR_GOOD 23 O Open-drain power good output pin. Pin is pulled low when one or more rails are disabled or not in regulation. DCDC1, DCDC2, and VCOM have no effect on this pin.(1) PWRUP 21 I Power-up pin. Pull this pin high to power up all output rails.(1) SCL 17 I Serial interface (I2C) clock input. SDA 18 I/O Serial interface (I2C) data input/output. TS 47 I Thermistor input pin. Connect a 10-kΩ NTC thermistor and a 43-kΩ linearization resistor between this pin and AGND. V3P3 46 O Output pin of 3.3-V power switch. VB 42 I Feedback pin for boost converter (DCDC1) and supply for VPOS LDO and VDDH charge pump. VB_SW 40 O Boost converter switch out (DCDC1). VCOM 15 O Filter pin for panel common-voltage driver. VCOM_CTRL 12 I VCOM enable. Pull this pin high to enable the VCOM amplifier. When pin is pulled low and VN is enabled, VCOM discharge is enabled.(2) VCOM_DIS 14 I Discharge pin for VCOM. Connect to ground to discharge VCOM to ground whenever VCOM is disabled. Leave floating if discharge function is not desired. VCOM_PWR 16 I Internal supply input pin to VCOM buffer. Connect to the output of DCDC2. VDDH_D 34 O Base voltage output pin for positive charge pump (CP1). VDDH_DIS 35 I Discharge pin for VDDH. Connect to VDDH to discharge VDDH to ground whenever the rail is disabled. Leave floating if discharge function is not desired. VDDH_DRV 36 O Driver output pin for positive charge pump (CP1). VDDH_FB 33 I Feedback pin for positive charge pump (CP1). VDDH_IN 37 I Input supply pin for positive charge pump (CP1). VEE_D 30 O Base voltage output pin for negative charge pump (CP2). VEE_DIS 29 I Discharge pin for VEE. Connect a resistor from VEE _DIS to VEE to discharge VEE to ground whenever the rail is disabled. Leave floating if discharge function is not desired. VEE_DRV 28 O Driver output pin for negative charge pump (CP2). VEE_FB 31 I Feedback pin for negative charge pump (CP2). VEE_IN 27 I Input supply pin for negative charge pump (CP2) (VEE). VIN 10 I Input power supply to general circuitry. VIN3P3 45 I Input pin to 3.3-V power switch. VIN_P 24 I Input power supply to inverting buck-boost converter (DCDC2). VN 26 I Feedback pin for inverting buck-boost converter (DCDC2) and supply for VNEG LDO and VEE charge pump. VNEG 3 O Negative supply output pin for panel source drivers. VNEG_DIS 9 O Discharge pin for VNEG. Connect to VNEG to discharge VNEG to ground whenever the rail is disabled. Leave floating if discharge function is not desired. VNEG_IN 4 I Input pin for LDO2 (VNEG). VN_SW 25 O Inverting buck-boost converter switch out (DCDC2). VPOS 44 O Positive supply output pin for panel source drivers. VPOS_DIS 19 I Discharge pin for VPOS. Connect a resistor from VPOS_DIS to VPOS to discharge VPOS to ground whenever the rail is disabled. Leave floating if discharge function is not desired. VPOS_IN 43 I Input pin for LDO1 (VPOS). VREF 1 O Filter pin for 2.25-V internal reference to ADC. WAKEUP 5 I Wake up pin (active high). Pull this pin high to wake up from sleep mode. IC accepts I2C commands after WAKEUP pin is pulled high but power rails remain disabled until PWRUP pin is pulled high.(3) Thermal Pad — — The thermal pad is internally connected to the PBKG pin. Connect the thermal pad to the VN pin with a short, wide trace. A wide copper trace improves heat dissipation. Do not connect the thermal pad to ground. |
