10 / 59 page  www.ti.com TPS65013 SLVS517A – AUGUST 2004 – REVISED JANUARY 2005 PIN ASSIGNMENTS (continued) Terminal Functions TERMINAL I/O DESCRIPTION NAME NO. CHARGER SECTION Charger input voltage from ac adapter. The AC pin can be left open or can be connected to AC 40 I ground if the charger is not used. Charger input voltage from USB port. The USB pin can be left open or can be connected to USB 43 I ground if the charger is not used. ISET 37 I External charge current setting resistor connection for use with ac adapter VBAT_A 41 I Sense input for the battery voltage. Connect directly with the battery. VBAT_B 42 O Power output of the battery charger. Connect directly with the battery. TS 38 I Battery temperature sense input PG 11 O Indicates when a valid power supply is present for the charger (open drain) AGND2 44 Analog ground connection. All analog ground pins are connected internally on the chip. PowerPAD™ - Connect the PowerPAD to GND SWITCHING REGULATOR SECTION AGND3 45 Analog ground connection. All analog ground pins are connected internally on the chip. VINMAIN_A, 7,8 I Input voltage for VMAIN step-down converter. This must be connected to the same voltage VINMAIN_B supply as VINCORE and VCC. L1_A, L1_B 9,10 Switch pin of VMAIN converter. The VMAIN inductor is connected here. VMAIN 13 I VMAIN feedback voltage sense input, connect directly to VMAIN Power supply for digital and analog circuitry of MAIN and CORE dc-dc converters. This VCC 6 I must be connected to the same voltage supply as VINCORE and VINMAIN. Also supplies serial interface block PGND1_A, Power ground for VMAIN converter 15,16 PGND1_B Input voltage for VCORE step-down converter. This must be connected to the same voltage VINCORE 5 I supply as VINMAIN and VCC. L2 4 Switch pin of VCORE converter. The VCORE inductor is connected here. VCORE 48 I VCORE feedback voltage sense input, connect directly to VCORE PGND2 46 Power ground for VCORE converter LDO REGULATOR SECTION AGND1 21 Analog ground connection. All analog ground pins are connected internally on the chip. VINLDO1 22 I Input voltage for LDO1 VLDO1 24 O Output voltage for LDO1 VFB_LDO1 23 I Feedback input from external resistive divider for LDO1 VINLDO2 19 I Input voltage for LDO2 VLDO2 20 O Output and feedback voltage for LDO2 DRIVER SECTION LED2 2 O LED driver, with blink rate programmable via serial interface VIB 3 O Vibrator driver, enabled via serial interface CONTROL AND I2C SECTION PS_SEQ 14 I Sets power-up/down sequence of step-down converters PB_ONOFF 47 I Push-button enable pin, also used to wakeup processor from low-power mode BATT_COVER 39 I Indicates if battery cover is in place HOT_RESET 31 I Push-button reset input used to reboot or wakeup processor via TPS65013 MPU_RESET 32 O Open-drain reset output generated by user activated HOT_RESET Open-drain system reset output, generated according to the state of the VMAIN output RESPWRON 33 O voltage. If the main output is disabled, RESPWRON is active (i.e., low). TPOR 27 I Sets the reset delay time at RESPWRON. TPOR = 0: Tn(RESPWRON) = 100 ms. TPOR = 1: Tn(RESPWRON) = 1 s. 10 |
