VIBRATOR DRIVER
The VIB open drain output is provided to drive a vibrator motor, controlled via the serial interface register
VDCDC2. It has a maximum dropout of 0.5 V at 100-mA load. Typically an external resistor is required to limit
the motor current, and a freewheel diode to limit the VIB overshoot voltage at turnoff.
LED2 OUTPUT
The LED2 output can be programmed in the same way as the PG output to blink or to be permanently on or off.
The LED2_ON and LED2_PER registers are used to control the blink rate. For both PG and LED2, the minimum
blink on time is 10 ms and this can be increased in 127 10 ms-steps to 1280 ms. For both PG and LED2, the
minimum blink period is 100 ms and this can be increased in 127 100-ms steps to 12800 ms.
INTERRUPT MANAGEMENT
The open drain INT pin is used to combine and report all possible conditions via a single pin. Battery and chip
temperature faults, precharge timeout, charge timeout, taper timeout and termination current are each capable of
setting INT low, i.e. active. INT can also be activated if any of the regulators are below the regulation threshold.
Interrupts can also be generated by any of the GPIO pins programmed to be inputs. These inputs can be
programmed to generate an interrupt either at the rising or falling edge of the input signal. It is possible to mask
an interrupt from any of these conditions individually by setting the appropriate bits in the MASK1, MASK2 or
MASK3 registers. By default, all interrupts are masked. Interrupts are stored in the CHGSTATUS, REGSTATUS
and DEFGPIO registers in the serial interface. CHGSTATUS and REGSTATUS interrupts are acknowledged by
reading these registers. If a 1 is present in any location then the TPS65010 automatically sets the corresponding
bit in the ACKINT1 or ACKINT2 registers and releases the INT pin. The ACKINT register contents are
self-clearing when the condition, which caused the interrupt, is removed. The applications processor should not
normally need to access the ACKINT1 or ACKINT2 registers.

The HOT_RESET input is used to generate an MPU_RESET signal for the application processor.
TheHOT_RESET pin could be connected to a user-activated button in the application. It can also be used to exit
low power mode, in this case the TPS65010 waits until the VCORE voltage has stabilized before generating the
MPU_RESET pulse. The MPU_RESET pulse is active low for t
(mpu_nreset)
sec. HOT_RESET has an internal 1-M
pull up to V
CC
.
The PB_ONOFF input can be used to exit LOW POWER MODE. It is typically driven by a user-activated
push-button in the application. Both HOT_RESET and PB_ONOFF are de-bounced internally by the TPS65010.
Typical de-bounce time is 56 ms. PB_ONOFF has an internal 1-M
pull down.
PB_ONOFF, BATT_COVER and UVLO events also cause a normal, maskable interrupt to be generated and are
noted in the REGSTATUS register.
Interrupt events are always captured; thus when an interrupt source is unmasked, INT may immediately go active
due to a previous interrupt condition. This can be prevented by first reading the relevant STATUS register before
unmasking the interrupt source.
If an interrupt condition occurs then the INT pin is set low. The CHGSTATUS, REGSTATUS and DEFGPIO
registers should be read. Bit positions containing a 1 (or possibly a 0 in DEFGPIO) are noted by the CPU and the
corresponding situation resolved. The reading of the CHGSTATUS and REGSTATUS registers automatically
acknowledges any interrupt condition in those registers and blocks the path to the INT pin from the relevant
bit(s). No interrupt should be missed during the read process since this process starts by latching the contents of
the register before shifting them out at SDAT. Once the contents have been latched (takes a couple of
nanoseconds), the register is free to capture new interrupt conditions. Hence the probability of missing anything
is, for practical purposes, zero.
The following describes how registers 0x01 (CHGSTATUS) and 0x02 (REGSTATUS) are handled:
CHGSTATUS(5,0) are positive edge set. Read of set CHGSTATUS(5,0) bits sets ACKINT1(5,0) bits.
CHGSTATUS(7-6,4-1) are level set. Read of set CHGSTATUS(7-6,4-1) bits sets ACKINT1(7-6,4-1) bits.
CHGSTATUS(5,0) clear when input signal low and ACKINT1(5,0) bits are already set.
CHGSTATUS(7-6,4-1) clear when input signal is low.
ACKINT1(7-0) clear when CHGSTATUS(7-0) is clear.
REGSTATUS(7-5) are positive edge set. Read of set REGSTATUS(7-5) bits sets ACKINT2(7-5) bits.
