Notes:
1. Transient capability with external 100 Ω resistor in series with VP pin and supply.
2. Exceeding these limits may cause a malfunction or permanent damage to the device.
3. Exceeding the limits on SCLK, SI, CS, SFPD, or RST pins may cause permanent damage to the device.
4. With output OFF.
5. Continuous output current rating so long as maximum junction temperature is not exceeded. Operation at 125°C ambient temperature will
require maximum output current computation using package RJA.
6. ESD data available upon request.
7. ESD1 testing is performed in accordance with the Human Body Model (CZap = 200 pF, RZap = 1500 Ω).
8. ESD2 testing is performed in accordance with the Machine Model (CZap = 200pF, RZap = 0 Ω).
9. Maximum output clamp energy capability at 150°C junction temperature using a single non-repetitive pulse method.
10. Maximum power dissipation at indicated junction temperature with no heat sink used.
11. Lead soldering temperature limit is for 10 seconds maximum duration; not designed for immersion soldering; exceeding these limits may
cause malfunction or permanent damage to the device.Contact Motorola Sales Office for device immersion soldering time/temperature limits.
12. Thermal resistance from Junction-to-Ambient with all outputs ON and dissipating equal power.
13. Thermal resistance from Junction -to-Ambient with a single output ON.


Description

The 33291L device is an eight output, low side power switch with 8-bit serial input control. The 33291L is a versatile circuit designed for automotive applications, but is well suited for other environments. The 33291L incorporates SMAROSTM technology, with CMOS logic, bipolar/MOS analog circuitry, and DMOS power MOSFETs. The 33291L interfaces directly with a microcontroller to control various inductive or incandescent loads.

The circuit's innovative monitoring and protection features include: Very Low Standby Current, SPI Cascade Fault Reporting Capability, Internal 53 V Clamp on Each Output, Output Specific Diagnostics, Independent Shutdown of Outputs.

The device is parametrically specified over an ambient temperature range of -40°C TA 125°C and 9.0 V VPWR 16 V supply.
