MC33880PEW数据手册恩XP中文资料规格书

描述 Description

The NXP® MC33880 is an 8-output hardware configurable high side/low side switch with 8-bit serial input control using the serial peripheral interface (SPI).
Two of the outputs can be controlled directly via MCU for pulse-width modulation (PWM) applications
Controls various inductive or incandescent loads by directly interfacing with a MCU
Innovative monitoring and protection features include very low standby currents, “cascadable” fault reporting, internal 40 V output clamping for low side configurations, internal -20 V output clamping for high side configurations, output specific diagnostics, and independent shutdown of outputs.

特性 Features

• Designed to operate 5.5 V ≤ VPWR ≤ 24.5 V
• 8-bit SPI for control and fault reporting, 3.3/ 5.0 V compatible
• 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 Ohm at 25 °C typical
• Short circuit detect and current limit with autoretry
• Independent over-temperature protection
• 32-pin SOICW has pins 8, 9, 24, and 25 grounded for thermal performance
