What are the key features of TPIC6B596N-P2?
- 8 open-drain power DMOS outputs rated at 50 V and 150 mA each enable direct relay, solenoid, and LED string drive without external transistors or flyback diodes
- SPI-compatible serial shift-register interface (SER, SRCK, RCK) allows 8 high-current outputs to be controlled from just 3 microcontroller GPIO pins, saving I/O resources
- Built-in clamp diodes on all 8 drain outputs suppress inductive kickback from relay coils and solenoids up to 50 V, eliminating external flyback diode arrays
- 20-DIP through-hole package with -P2 RoHS-compliant marking supports hand-soldering prototyping and field-repair of industrial control panels
What is TPIC6B596N-P2 used for?
TPIC6B596N-P2 drives solenoid valves, relay coils, and high-power LED strings in industrial automation and factory control systems using a minimal 3-wire SPI link from a microcontroller. It is widely used in printing machine head drivers and ticket dispensers where 8 independently controllable 150 mA output channels replace 8 discrete transistor driver circuits. The device also suits automotive body electronics prototypes where 50 V-rated open-drain outputs handle inductive lamp and motor loads while the shift register interface reduces wiring harness pin count.

Frequently Asked Questions
What are the voltage and current ratings of TPIC6B596N-P2 drain outputs for driving industrial loads?
Each of the 8 open-drain DMOS outputs on TPIC6B596N-P2 is rated for 50 V drain-source voltage and 150 mA continuous drain current. All 8 outputs can switch simultaneously, giving a total aggregate current handling of 1.2 A when driving 8 parallel 150 mA loads such as small relay coils or solenoid valve coils.
How does TPIC6B596N-P2 eliminate external flyback protection diodes in relay drive circuits?
TPIC6B596N-P2 integrates internal clamp diodes on all 8 drain outputs, clamping inductive kickback to the supply rail when relay or solenoid coils are de-energized. The clamp diodes handle spikes up to 50 V, removing the need for 8 discrete 1N4007 or BAV99 flyback diodes and reducing BOM cost and PCB footprint by approximately 8 components.
How many microcontroller GPIO pins are required to control all 8 outputs of TPIC6B596N-P2?
TPIC6B596N-P2 requires only 3 GPIO pins from the microcontroller: a serial data input (SER), a shift clock (SRCK), and a register clock (RCK). An optional output enable (OE) pin provides group-level enable/disable. This 3-wire SPI approach frees 5 GPIO pins compared to driving 8 discrete transistors directly.
Can TPIC6B596N-P2 devices be daisy-chained to drive 16 or 24 loads from the same SPI bus?
Yes, TPIC6B596N-P2 supports serial daisy-chaining by connecting the serial output (SER OUT) of the first device to the SER IN of the next. Two devices control 16 independent 50 V / 150 mA loads; three devices control 24 loads—all from the same 3 microcontroller GPIO pins by clocking 16 or 24 bits respectively per update cycle.
