MC33298
Octal Serial Switch with
Serial Peripheral Interface I/O
The MC33298 is an eight output low side power switch with 8 bit serial input
control. The MC33298 is a versatile circuit designed for automotive
applications, but is well suited for other environments. The MC33298
incorporates SMARTMOS™ technology, with CMOS logic, bipolar/MOS
analog circuitry, and DMOS power MOSFETs. The MC33298 interfaces
directly with a microcontroller to control various inductive or incandescent
loads. The circuit’s innovative monitoring and protection features are: very low
standby current, cascadable fault reporting, internal 65 V clamp on each
output, output specific diagnostics, and independent shutdown of outputs. The
MC33298 is parametrically specified over a temperature range of – 40°C ≤ TA
≤ +125°C ambient temperature and 9.0 V ≤ VPWR ≤ 16 V supply. The
economical 20 pin DIP and SO–24 wide body surface mount plastic packages
make the MC33298 very cost effective.

NOTES: 1. SPI inputs and outputs operational; Fault reporting may not be fully operational within this voltage range.
2. Value reflects normal operation (no faults) with all outputs “on.” Each “on” output contributes approximately 20 µA to IPWR. Each output experiencing
a “soft short” condition contributes approximately 0.5 mA to IPWR. A “soft short” is defined as any load current causing the output source current to
self–limit. A “hard” output short is a very low impedance short to supply.
3. For VDD less than the Undervoltage Lockout Threshold voltage, all data registers are reset and all outputs are disabled.
4. Output fault detect threshold with outputs programmed “off.” Output fault detect thresholds are the same for output opens and shorts.
5. Output “Off” Open Load Detect Current is the current required to flow through the load for the purpose of detecting the existence of an open condition
when the specific output is commanded to be “off.”
6. Output leakage current measured with output “off” and at 16 V.
7. This parameter is guaranteed by design but is not production tested.

SO (low–to–high) is for an output with internal conditions such that
the low–to–high transition of CSB causes the SO output to switch
from high–to–low.

NOTES: 1. SO (high–to–low) waveform is for SO output with internal
conditions such that SO output is low except when an output is
disabled as a result of detecting a circuit fault with CSB in a
High Logic state (e.g., open load).
2. SO (low–to–high) waveform is for SO output with internal
conditions such that SO output is high except when an output
is disabled as a result of detecting a circuit fault with CSB in
a High Logic state (e.g., shorted load).
