MCZ33880 Overview
Freescale Semiconductor Advance Information Document Number: 5.0, 6/2007 Configurable Octal Serial Switch with Serial Peripheral Interface I/O The 33880 device is an eight-output hardware-configurable highside/low-side switch with 8-bit serial input control. Two of the outputs can be controlled directly via microcontroller for Pulse Width Modulation (PWM) applications.
MCZ33880 Key Features
- Designed to Operate 5.5 V < VPWR < 24.5 V
- 8-Bit SPI for Control and Fault Reporting, 3.3 V/ 5.0 V patible
- Outputs Are Current Limited (0.8 A to 2.0 A) to Drive Incandescent Lamps
- Output Voltage Clamp Is +45 V (Typical) (Low-Side Drive) and 20 V (Typical) (High-Side Drive) During Inductive Switching
- Internal Reverse Battery Protection on VPWR
- Loss of Ground or Supply Will Not Energize Loads or Damage IC
- Maximum 5.0 µA IPWR Standby Current at 13 V VPWR up to 95°C
- RDS(ON) of 0.55 Ω at 25°C Typical
- Short Circuit Detect and Current Limit with Automatic Retry
- Independent Overtemperature Protection
