ZXCT1107Q/09Q/10Q AUTOMOTIVE COMPLIANT MICROPOWER CURRENT MONITOR Description Pin Assignments The ZXCT1107Q/09Q/10Q products are high-side unipolar current ZXCT1107Q Top View sense monitors. These devices eliminate the need to disrupt the ground plane when sensing a load current. 2 2 SS-- The wide common-mode input voltage range and low quiescent current, OOUTUT 11 coupled with SOT23 and SOT25 packages, make them suitable for a range of automotive applications. 3 3 S S++ The device is line powered and as such doesnt need a separate supply rail. ZXCT1109Q Top View Quiescent current is only 3A, thereby minimizing current sensing error. One external gain setting resistor increases versatility by permitting 2 2 S S++ wide gain ranges. OOUTUT 11 The ZXCT1107Q/09Q/10Q devices have been qualified to AEC-Q100 Grade 1 and are Automotive Compliant supporting PPAPs. 3 3 SS-- ZXCT1110Q Top View Features NC NC 1 1 55 SS-- Wide Supply and Common-Mode Voltage Range: 2.5V to 36V GGND ND 22 SOT23 and SOT25 Packages 3-Pin ZXCT1107Q/09Q 44 SS++ OOUTUT 33 5-Pin ZXCT1110Q Low Quiescent Current (3A) Extended Industrial Temperature Range -40 to +125C Applications Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free.

See ZXCT1107Q/09Q/10Q Pin Descriptions Package SOT23 SOT25 Description Name ZXCT1107Q ZXCT1109Q ZXCT1110Q OUT 1 1 3 Output pin (Note 5). Current output. This is the positive input of the current monitor and has a wide common-mode input range. This also acts as the analog supply and provides power to internal S+ 3 2 4 circuitry. The current through this pin varies with differential sense voltage. This is the negative input of the current monitor and has a wide common-mode S- 2 3 5 input range. GND 2 Ground pin and substrate connection. NC 1 No connection. Note: 5. For the ZXCT1107Q and ZXCT1109Q pin 1 (OUT) acts as both the output pin and substrate connection. This means that for the ZXCT1107Q and ZCT1109Q the minimum rail voltage that can be used is 2.5V + V (see applications section for more details).

These are stress ratings only functional operation of the device at conditions between maximum recommended operating conditions and absolute maximum ratings is not implied. Device reliability may be affected by exposure to absolute maximum rating conditions for extended periods of time. Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when handling and transporting these devices.) 2 of 17 ZXCT1107Q/09Q/10Q October 2018 Diodes Incorporated www.diodes.com Document number: DS37002 Rev. 3 - 2
