Advance Information
Dual/Hex Low-Side Switch with
Both SPI and Parallel Input Control
The 33397 is a low-side switch that is user configurable to be either two
333 moutputs (dual mode) or six 900 moutputs (hex mode). Each output
is internally current limited and short-circuit protected. Output fault detection
capability includes “off state” open loads and “on state” short-to-battery
conditions. Faults for each output are latched into the fault register and serially
shifted out during serial communication.
33397
DUAL/HEX LOW-SIDE SWITCH
Features
• User Configurable to be Either Two 333 mOutputs (Dual Mode) or Six
900 mOutputs (Hex Mode)
• Output Inductive Energy Clamps
• Parallel Input (3.3 V and 5.0 V Compatible) or Serial Peripheral Interface
(SPI) Control
• 8-Bit SPI Control and Fault Diagnostics
• Short-to-Battery Detection and Shutdown with Automatic Retry
• OFF-State Open-Circuit Detection
• Programmable Overvoltage Shutdown (VPWR Pin)
• Undervoltage Shutdown (VDD Pin)
• Sleep Mode—IDD 25 µA (1.0 µA Typical)
