NUCLEOG431RB中文资料意法半导体数据手册PDF规格书

特性 Features

• Based on the IPS4260LM quad low-side switch, which features:

– Operating range 8 to 50 V

– High Speed operation (trise, tfall < 1us)

– Process side operating current: configurable from 350 mA (per channel)

up to 2 A (parallelized channels)

– Low-power dissipation (RON(TYP) = 260 mΩ)

– Configurable low dissipative cutoff function in overload conditions

– Per-channel overload, short circuit, and thermal junction protections

– Fast decay of inductive loads with integrated catch diodes

– Open load detection

– Undervoltage lock-out

– Loss of supply / loss of ground protection

– HTSSOP20 package

• Galvanic isolation between logic and process sides by STISO620, STISO621

digital isolators and isolated DC-DC converter

• Selectable supply of the IPS4260LM from on board isolated dc-dc converter

(SW7 close 1-2), or from 24 V supply rail (SW7 close 2-3)

• Process side operating range: 10 V (SW7 close 1-2) or 10 to 30 V (SW7 close

2-3)

• Process side supply rail reverse polarity protections (J1 open when SW7 =

close 2-3)

• Application board logic side operating voltage 3.3 (SW1 close 1-2) or 5 V (SW1

close 2-3)

• Green LEDs for outputs on/off status (J6 close 1-2, 3-4, 5-6, 7-8)

• Open load detection enable (J7 close 1-2, 3-4, 5-6, 7-8) / disable (J7 open)

• Red LEDs for overload/thermal warning (D8) and open load (D7) diagnostic

• Selectable current limitation level (J8 close 1-2 = 0.5A, or 3-4 = 1A, or 5-6 =

2A)

• Cutoff enable (J8 open 7-8) / disable (J8 close 7-8) options

• Per channel overload diagnostic available on CN5[9,10] and CN8[5, 6]

• Easy parallelization of input signals (J9) and output channels (J10)

• Compatible with STM32 Nucleo development boards

• Equipped with Arduino® UNO R3 connectors

• RoHS and China RoHS compliant

• CE certified
