Product overview
Description
The L99SP08 Smart P-channel is an octa channel device made using STMicroelectronics BCD9sL technology, housed in a small QFN 5x5x0.9 mm 32+4L wettable flanks package. It is designed to support standby on functionality, when interacting with hybrid and monolitich STi²Fuse product family, as well as to drive loads in standalone mode, up to IOUTX DC current per channel.
Integrating a deep standby mode, the device fulfills highly stringent requirements for all those always active battery lines, providing ultra-low current consumption with the car in parking mode.
Real time diagnostic is available through the SPI bus (communication error, oscillator stuck, overtemperature, VCC and VOUT monitoring). In case of overtemperature, VDS overvoltage or IPEAK triggering, the device sets high EN pin, allowing the turn on of external devices, like STi²Fuse hybrid and monolithic devices (for further information on the usage of the L99SP08 in combination with the hybrid and monolithic STi2Fuse devices for parking mode functionality refer to the related application notes AN6025 and AN6371).
Built-in self-tests (BIST) are integrated to check the correct behavior of the device during its working life, allowing customer on demand activation, testing current ADC, voltage ADC, standby on current sense chain and P-channel stuck-on protection.
The device is also equipped with a nonvolatile memory (NVM) to allow the customer to set current thresholds (ITHRx) parameters, managing the standby on exit strategy.
Limp-home mode is enabled in case of reset of watchdog monitoring time-out event or LH (limp-home) pin is set to high. In this state each output is controlled by dedicated direct inputs (DIx).

All features
- AEC-Q100 qualified
- 8x P-channel with RON = 1 Ω
- Ultra low current consumption:
- 0 μA in deep standby mode
- 6 μA in standby on mode per channel
- 4x direct inputs to control channels status in limp-home mode
- 24-bit ST-SPI interface for device full configurability and standalone operation
- Limp-home mode set by dedicated pin
- Integrated ADC block to monitor:
- Outputs current in on state (both in normal and fail-safe mode)
- Battery and output voltages in both on and off state (in normal mode)
- Device junction temperature (TJ) in both on and off state
- Dual range ADC for current sensing
- 500 mA minimum peak current (per channel) to avoid undesired main switch triggering due to inrush transient current (microcontroller peripherals polling, contact monitoring…)
- Built in self test (BIST), actionable on demand, to monitor correct device behavior during its working life:
- Current ADC
- Voltage ADC
- Standby on current sense chain
- P-channel stuck-on protection
- Non-volatile memory (NVM) to configure current thresholds (ITHRx) automatically to exit standby ON state - two few times programmable (FTP) bits per channel
- Capacitive charging mode (CCM) in normal operation
- Protection–whose triggering generates main switch enable:
- Overtemperature shutdown (latch-off)
- Current shutdown (based on VDS monitoring)
- Integrated ESD protection
- QFN 5x5x0.9 mm 32+4L package with wettable flanks
- Compliant with European directive 2002/95/EC
