IPS8200HQ and IPS8200HQ-1 Octal Solid-State Relays
STMicroelectronics' octal high-side switches can drive capacitive, resistive, or inductive loads
STMicroelectronics' IPS8200HQ and IPS8200HQ-1 are octal high-side switches that can drive capacitive, resistive, or inductive loads with one side connected to ground (high-side switch). The ICs are designed in STMicroelectronics™ VI Power M0A6 Technology and assembled in a tiny QFN 8 mm x 6 mm x 0.9 mm 48L package.
The output stage is an N-channel PowerMOSFET with a typical RDS(ON) of 110 mΩ at ambient temperature, internally limited at 0.7 A minimum output current for IPS8200HQ meanwhile 1.0 A for IPS8200HQ-1 per channel. Both ICs operate from 10.5 V up to 36 V voltage recommended, but the breakdown voltage on the supply pin can reach 45 V. They can be driven by using a compatible I/Os 3.3 V/5 V logic supply. The ICs offer a selectable SPI or parallel driving interface on the logic side.
The SPI (embed four-wire SPI control) can work up to 5 MHz and can be selected to operate in 8 bits or 16 bits with parity check for communication robustness and extended diagnostic (case overtemperature, communication error, and power good information for valid supply voltage range recognition). Dedicated diagnostic pins report the detection of invalid voltage range on VCC rail (PG pin), case overtemperature (TWARN pin), SPI communication fault, or junction overtemperature (FAULT pin). In SPI mode, the daisy chain, the outputs enable/disable signal (for immediate power outputs ON/OFF), and the MCU freeze detection by the watchdog (used to detect the occurrence of a software fault of the host controller) are available.
Active per channel current limitation, combined with thermal shutdown, independent for each channel, protect the device against overload, overtemperature, and short-circuit. Additional embedded functions are loss of GND protection (guarantees automatic turns off the device outputs in case of ground disconnection) and undervoltage lockout. An internal LED matrix driver circuitry (4 rows, 2 columns) provides a visual indication, driving the 8 LEDs, of the status (ON or OFF) of each of the 8 output channels. The embedded DC/DC voltage regulator (100 mA) provides supply voltage to the LED matrix driver, SPI logic side, and inputs. It can be used to supply other external components if the application requires it, for example, optocouplers or digital isolators.
