Each channel has independent OFF-state open-load sense, ON-state shorted-load/short-to-battery protection, over-battery-voltage-lockout protection, and over-temperature sense with fault status reported through the serial interface. The device also provides inductive voltage transient protection for each drain output. The TPIC2603 drives inductive and resistive loads such as relays, valves, and lamps.

Each string of data must consist of 8 or 16 bits of data. A logic high input data bit turns the respective output channel ON and a logic low data bit turns it OFF. CS must be transited high after all of the serial data has been clocked into the device. A low-to-high transition of CS transfers the last six bits of serial data to the output buffer, places the serial data out (SDO) terminal in a high-impedance state, and re-enables the fault register. Fault data for the device is sent out the SDO terminal. The first bit of the shift register is exclusively ORed with the fault registers. When a fault exists, the SDI data is inverted as it is transferred out of SDO. Fault data consists of fault flags for over-temperature (bit 6) and shorted/open-load (bits 0-5) for each of the six output channels. Fault register bits are set or cleared asynchronously, when CS is high to reflect the current state of the hardware. The fault must be present when CS is transited from high to low to be captured and reported in the serial fault data. New faults cannot be captured in the serial register when CS is low.

Switching Characteristics serial interface Control information is transferred into the TPIC2603 through the serial interface. The serial interface consists of a serial clock (SCLK), chip select (CS), serial data input (SDI), and serial data output (SDO). Serial data is shifted, most significant bit (MSB) first, into the SDI shift register on the rising edge of the first SCLK after CS has transited from high to low. The controller must shift either eight bits or sixteen bits of data into the device with the last six bits of input data containing control information for the output drivers. Data bits preceeding the output control information should be set to 0. A low-to-high transition on CS latches the contents of the last six bits of the serial shift register into the output buffer. A low input to SDI turns the corresponding parallel output OFF and a high input will turn the output ON (see Figure 2). 1 2 3 4 5 SCLK CS SDI NEW DATA 0 DRAIN5 DRAIN4 DRAIN3 DRAIN2 DRAIN1 DRAIN0 OFF ON ON OFF OFF ON Figure 2.

Fault status for the TPIC2603 is captured as CS transits low. The fault interface monitors the SDI terminal and exclusively ORs the respective input control bit with the corresponding fault information bit stored in the fault register. Each exclusive ORed fault bit is transferred out the SDO terminal on the rising edge of the SCLK. Serial data can be transferred in 8-bit or 16-bit words as illustrated in Figure 4, with fault data appearing in the first 8-bits of serial output data. The CS must be transited high after the serial transfer has completely latched the new control data into the output control buffer and re-enable fault reporting on the device (see Figures 3 and 4). 1 2 3 4 5 6 7 8 OT FLT5 FLT4 FLT3 FLT2 FLT1 FLT0 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0 SCLK CS SDO 3-STATE N/A Bit7 3-STATE NA = Unused OT = Over-temperature fault bit FLT5 = Shorted or open-load fault on channel 5 FLT4 = Shorted or open-load fault on channel 4 FLT3 = Shorted or open-load fault on channel 3 FLT2 = Shorted or open-load fault on channel 2 FLT1 = Shorted or open-load fault on channel 1 FLT0 = Shorted or open-load fault on channel 0 NOTE A: MSB is the first bit transferred.

Each channel offers two levels of protection from over-current conditions. The first level is a current-limit protection which through the internal FET prevents the switching current from exceeding the on-state current limit. The second level of protection transits the output to a low duty cycle PWM mode when the current exceeds the over-current sense threshold. The PWM mode protection is enabled approximately 70 µs after the output has been turned on. The output remains in the PWM mode until the shorted-load condition has been corrected and then automatically returns to normal operation.

When the output turns OFF, a 40-µA current source switches onto the drain. Under normal conditions, the load provides adequate current to overcome the current source and the drain voltage remains above the open-load detection threshold. When the output is open, then the current source pulls the drain low and an open-load condition is flagged. The open-load test is enabled approximately 70 µs after the output turns OFF to allow the drain to stabilize. Figure 6 illustrates device operation under open-load conditions.

Open-Load Condition over-voltage sensing and protection The TPIC2603 monitors the Vbat input terminal to protect the device and load from over-battery voltage conditions. The device disables all of the drain outputs when Vbat goes above 35 V. An over-battery voltage hysteresis is provided to prevent the outputs from transiting ON and OFF erratically near the over-voltage threshold. The device automatically returns to normal operation after the over-voltage condition has been corrected. Figure 7 illustrates device operation under an over-battery voltage condition.

When the junction temperature goes above approximately 170°C, the fault logic sets the global over-temperature fault bit. An over-temperature fault is reported using the serial interface on bit 6 (for 8-bit configuration) or bit 14 (for 16-bit configuration). The global over-temperature fault output in the serial data is exclusively ORed with the second bit (bit 6 for 8-bit configuration or bit 14 for 16-bit configuration) of data input to the SDI terminal. Bit 6 or bit 14 of the input data should be set low. Over-temperature faults are for informational purposes only and do not affect the state of the drains.
