HA12187FP Bus Interface Driver/Receiver IC ADE-207-174A (Z) 2nd Edition Jun. 1999 Description The HA12187FP was developed to be used as a bus interface driver/receiver IC in automotive audio equipment controllers. It implements a two-wire serial bus. Functions • Two-input OR circuit • Input comparator circuit • Current output driver circuit • Receiver input comparator circuit • Receiver output circuit • Standby circuit Features • Supports two data inputs (Pins 1 and 3 are the input pins) • Comparators with hysteresis characteristics were adopted for the inputs • Current drive output drivers adopted (Output current: 3.8 mA typical) • Comparators with hysteresis characteristics were adopted for the receivers • Wide receiver common-mode input operating range (Common-mode input operating range: 0 to 5 V typical) • The driver output and the receiver input can withstand high voltages (Maximum rating: 18 V) • Standby function (The IC enters standby mode when pin 8 goes low) • Operating power-supply voltage range: 5 V ±0.5 V HA12187FP Block Diagram VCC 7 S1 1 + Driver output (current) – S2 3 8 R 2 BIAS 5 – Receiver output COM + 4 Rev.2, Jun. 1999, page 2 of 23 BUS (+) 6 BUS (–) HA12187FP Pin Functions Pin No. Symbol Function 1 S1 Data input Equivalent Circuit 1 2 R out 20 k Receiver output SW 2 100 SW 3 S2 Data input 3 4 GND GND 5 BUS (–) Bus output (–) Receiver input (–) 6 BUS (+) Bus output (+) Receiver input (+) 20k SW I Receiver input (+) 6 VREF Receiver input (–) 5 I 7 VCC Power supply 8 STB Standby control input 8 20 k 100 k Rev.2, Jun. 1999, page 3 of 23 HA12187FP Absolute Maximum Ratings (Ta = 25°C) Item Symbol Ratings Unit Power-supply voltage VCC 7 V Allowable power dissipation Pd 400 mW Operating temperature Topr –40 to 85 °C Storage temperature Tstg –55 to 125 °C Input voltage Vin –1.0 to 6.7 V Bus input voltage Bus 18 V Note: Recommended operating power supply voltage range: 5 V ±0.5 V Rev.2, Jun. 1999, page 4 of 23 Notes Ta ≤ 85°C HA12187FP Electrical Characteristics (VCC = 5.0 V, Ta = 25°C) Test Pin Test Circuit V1 = 0 V → 5 V, V3 = 0 V With the potential difference between pin 5 and pin 6 120 mV or more 1 Figure 1 V V1 = 5 V → 0 V, V3 = 0 V With the potential difference between pin5 and pin 6 20 mV or less 1 1 µA V1 = 5 V, V3 = 0 V 1 — 1 µA V1 = 0 V, V3 = 0 V 1 3.5 — — V V3 = 0 V → 5 V, V1 = 0 V With the potential difference between pin 5 and pin 6 120 mV or more 3 — — 1.5 V V3 = 5 V → 0 V, V1 = 0 V With the potential difference between 5 and pin 6 20 mV or less 3 High-level input IIHS2 current — — 1 µA V1 = 0 V, V3 = 5 V 3 Low-level input current IILS2 — — 1 µA V1 = 0 V, V3 = 0 V 3 IOH 3.0 3.8 4.8 mA IOH = | VOHD+ – VOHD– | / 62 Ω 5, 6 Low-level output IOL leakage current — — 1 µA Pin 5 voltage = VOP– IOL = | VOP+ – VOP– | / RI 5, 6 Reference operating voltage (+) VOP+ 2.3 2.5 2.7 V V1 = 0 V, V3 = 0 V 6 Reference operating voltage (–) VOP– 2.3 2.5 2.7 V V1 = 0 V, V3 = 0 V 5 Current drain 1 ICCH 5.5 7.3 9.5 mA V1 = 5 V, V3 = 0 V 7 Figure 1 Current drain 2 ICCL 1.7 2.2 2.7 mA V1 = 0 V, V3 = 0 V 7 Figure 1 Item S1 S2 Symbol Min Typ Max Unit Test Conditions High-level input VIHS1 voltage 3.5 — — V Low-level input voltage — — 1.5 High-level input IIHS1 current — — Low-level input current — High-level input VIHS2 voltage Low-level input voltage Driver High-level output current VILS1 IILS1 VILS2 Figure 1 Figure 1 Rev.2, Jun. 1999, page 5 of 23 HA12187FP Electrical Characteristics (VCC = 5.0 V, Ta = 25°C) (cont) Item Symbol Test Pin Test Circuit Min Typ Max Unit Test Condition — 80 120 mV V6 = 0 → 5 V, pin 2 = 4 V 2 or more, V1 = 0V, V3 = 0V, V5 = VOP–, VIH1 = V6 – V5 Figure 2 20 45 — mV V6 = 5 → 0 V, pin 2 = 1 V 2 or less, V1 = 0 V, V3 = 0 V, V5 = VOP–,VIL1 = V6 – V5 Figure 2 Input hysteresis VIHYS1 voltage (1) 10 35 60 mV VIHYS1 = VIH1 – VIL1 High-level common-mode input voltage VIHCOM 4.5 — — V V5 = 0 → 5 V, pin 2 = 4 V or more, V1 = 0 V, V3 = 0 V, V6 – V5 = 120 mV 5 Figure 2 Low-level common-mode input voltage VILCOM 5 — — V V5 = 0 → 5 V, pin 2 = 1 V 5 or less, V1 = 0 V, V3 = 0 V, V6 – V5 = 20 mV Figure 2 Receiver input 1 resistance* RI 25 35 45 kΩ V1 = 0 V, 0.6 V RI = I1− I2 5, 6 Figure 3 High-level output voltage VOH 4.5 — — V V1 = 5 V, V3 = 0 V 2 Figure 1 — — 1.0 V V1 = 0 V, V3 = 0 V 2 Figure 1 Power supply off output IOLEAK leakage current — — 1 µA VCC off, V8 = 0 V, V6 = 5 V, 5, 6 V1 = 0 V, V3 = 0 V, SW1 on Figure 4 STB on voltage VSTBon — — 1.5 V V8 = 5 → 0 V, V1 = 5 V, V8 7 when ICC ≤ 20 µA Figure 4 STB off voltage VSTBoff 3.5 — — V V8 = 0 → 5 V, V1 = 5 V, V8 7 when ICC ≥ 4.5 mA Figure 4 Standby mode current drain ICCstb — 10 20 µA V1 = 5 V, V3 = 0 V, V8 = 0 7 V Figure 4 Standby mode leakage Istb-Leak — current — 1 µA V1 = 5 V, V3 = 0 V, V8 = 0 5, 6 V, V6 = 5 V, SW1 on Figure 4 Delay time (L → H) DLY1 — 600 800 nS See the operating waveform figure 2 Figure 5 Delay time (H → L) DLY2 — 450 800 nS See the operating waveform figure 2 Figure 5 Recei High-level input VIH1 ver voltage (1) Low-level input voltage (1) VIL1 Low-level output VOL voltage Note: 1.
