Description

This STPIC6C595 is a monolithic, mediumvoltage, low current power 8-bit shift register designed for use in systems that require relatively moderate load power such as LEDs. The device contains a built-in voltage clamp on the outputs for inductive transient protection. Power driver applications include relays, solenoids, and other low-current or medium-voltage loads.

The device contains an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. Data transfers through both the shift and storage register clock (SRCK) and the register clock (RCK), respectively. The device transfers data out the serial output (SER OUT) port on the rising edge of SRCK. The storage register transfers data to the output buffer when shift register clear (CLR) is high. When CLR is low, the input shift register is cleared. When output enable

(G) is held high, all data in the output buffer is held low and all drain output are off. When G is held low, data from the storage register is transparent to the output buffer.

Table 1. Device summary

When data in the output buffers is low, the DMOS transistor outputs are off. When data is high, the DMOS transistor outputs have sink-current capability. The SER OUT allows for cascading of the data from the shift register to additional devices.

Output are low-side, open-drain DMOS transistors with output ratings of 33 V and 100 mA continuous sink-current capability. Each output provides a 250 mA maximum current limit at

TC = 25 °C. The current limit decreases as the junction temperature increases for additional device protection. The device also provides up to 1.5 kV of ESD protection when tested using the human-body model and 150 V machine model.

The STPIC6C595 is characterized for operation over the operating case temperature range of -40 °C to 125 °C.

2 Maximum rating

Stressing the device above the rating listed in the “absolute maximum ratings” table may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other conditions above those indicated in the operating sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

4Drain supply voltage = 15 V, starting junction temperature (TJS) = 25 °C. L = 1.5 H and IAS = 200 mA (see Fig. 11 and 12)

5Technique should limit TJ - TC to 10 °C maximum

6These parameters are measured with voltage sensing contacts separate from the currentcarrying contacts.

7Nominal current is defined for a consistent comparison between devices from different sources. It is the current that produces a voltage drop of 0.5 V at TC = 85 °C.
