Advance Information
Six-Output Low-Side Switch with
SPI and Parallel Input Control
The 33882 is a smart six-output low-side switch able to control system loads
up to 1.0 A. The six outputs can be controlled via both serial peripheral
interface (SPI) and parallel input control, making the device attractive for fault-
tolerant system applications. There are two additional 30 mA low-side
switches with SPI diagnostic reporting (with parallel input control only).
The 33882 is designed to interface directly with industry-standard
microcontrollers via SPI to control both inductive and incandescent loads.
Outputs are configured as open-drain power MOSFETs incorporating internal
dynamic clamping and current limiting. The device has multiple monitoring and
protection features, including low standby current, fault status reporting,
internal 52 V clamp on each output, output-specific diagnostics, and protective
shutdown. In addition, it has a mode select terminal affording a dual means of
input control.
Features
• Outputs Clamped for Switching Inductive Loads
• Very Low Operational Bias Currents (< 2.0 mA)
• CMOS Input Logic Compatible with 5.0 V Logic Levels
• Load Dump Robust (60 V Transient at VPWR on OUT0–OUT5)
• Daisy Chain Operation of Multiple Devices Possible
• Switch Outputs Can Be Paralleled for Higher Currents
• RDS(ON) of 0.4 Ω per Output (25°C) at 13 V VPWR
• SPI Operation Guaranteed to 2.0 MHz

Definition
These input terminals control two output channels each when the MODE terminal is
pulled high. These terminals may be connected to pulse width modulated (PWM)
outputs of the control IC while the MODE terminal is high. The states of these terminals
are ignored during normal operation (MODE terminal low) and override the normal
inputs (serial or parallel) when the MODE terminal is high. These terminals have internal
active 25 µA pull-downs.
These are parallel input terminals. These terminals have internal 25 µA active pull-
downs.
Each terminal is one channel's drain, sinking current for the respective load.
Ground continuity is required for the outputs to turn on.
This terminal is connected to battery voltage. A decoupling capacitor is required from
VPWR to ground.
The MODE terminal is connected to the MODE terminal of the control IC. This terminal
has an internal active 25 µA pull-up.
The Serial Input terminal is connected to the SPI Serial Data Output terminal of the
control IC from where it receives output command data. This input has an internal
active 25 µA pull-down and requires CMOS logic levels.

Notes
25. Output Rise and Fall time measured at 10% to 90% and 90% to 10% voltage points respectively across 15 Ω resistive load to a VBAT of
15 V, VPWR = 15 V.
26. Output Turn-ON Delay Time measured from rising edge (3.0 V) VIN (CS for serial) to 90% VO using a 15 Ω load to a VBAT of 15 V,
VPWR = 15 V.
27. Output Turn-OFF Delay Time measured from falling edge (1.0 V) VIN (3.0 V rising edge of CS for serial) to 10% VO using a 15 Ω load to a
VBAT of 15 V, VPWR = 15 V.
28. The shorted output is turned ON during tSS to retry and check if the short has cleared. The shorted output is in current limit during tSS. The
tSS is measured from the start of current limit to the end of current limit.
29. The Short Fault Refresh Time is the waiting period between tSS retry signals. The shorted output is disabled during this refresh time. The
tREF is measured from the end of current limit to the start of current limit.
30. The tOS(OFF) is measured from the time the faulted output is turned OFF until the fault bit is available to be loaded into the internal fault
register. To guarantee a fault is reported on SO, the falling edge of CS must occur at least 100 µs after the faulted output is off.
31. The tOS(ON) is measured from the time the faulted output is turned ON until the fault bit is available to be loaded into the internal fault register.
To guarantee a fault is reported on SO, the falling edge of CS must occur at least 12 ms after the faulted output is ON.
32. Percent Output Short Fault ON Duty Cycle is defined as (tSS) ÷ (tREF) x 100. This specification item is provided FYI and is not tested.
33. Parameter is not tested and values suggested are for system design consideration only in preventing the occurrence of double pulsing.
